Short Sleeve or Long Sleeve: Choosing School Shirts

Choosing school shirts in South Africa comes down to two sleeves and one decision: short or long, and how many of each. A shirt that fits at the shoulder, the collar and the wrist will outlast a shirt bought two sizes up for a growth spurt that never arrives on schedule.

We sell both cuts from our Johannesburg warehouse and deliver nationwide, and the same question lands in our inbox every January. Which one does my child need? The answer depends on the school's rule, the terms your province runs, and whether a jersey or blazer sits over that shirt for most of the day.

This guide takes it in the order that matters: the rule, the fit, the weather, then the money.

The Rule Schools Actually Enforce

Uniform rules are set by each school's governing body, not by the national department. The Department of Basic Education issues guidelines and each school writes its own code on top of them. That is why one primary school in Benoni insists on short sleeves in Terms 1 and 4 while a school three suburbs away allows either cut all year.

Two documents sit above the school's own list. The 2015 School Uniform Guidelines are one. The other is the procurement circular that the National Consumer Commission restates in its consumer alert: exclusive supply deals should be limited to items carrying the school identity, such as badges, and parents should not be pushed to one preferred supplier. In January the Competition Commission was still flagging restrictive deals and the price gap between uniform specialists and general retailers.

Then there is enforcement in the schoolyard, which is not the same as the written rule. Collar style, colour and the badge are hard requirements. Sleeve length is usually soft. Children are rarely sent home for short sleeves in February. They are sent home for the wrong shade of white or a shirt with no badge.

So read the school's uniform list first, and check three things on it:

• Does it name a sleeve length at all, or only a colour, collar and badge?
• Does it separate a summer and winter uniform, or run one code all year?
• Does it require long sleeves on blazer days, for speech day, or from a certain grade?

If the list says nothing about sleeves, the choice is yours.

Read the uniform list, not the class WhatsApp group. Half the rules parents repeat in January are habits, not policy.

How Should a School Shirt Fit?

Fit beats fabric every time. A cheaper shirt that fits looks better in November than an expensive one that does not, because an oversized shirt hangs off the shoulders instead of on the body.

Shoulder. The shoulder seam sits on the point of the shoulder, not inside it and not past it. This is the one measurement nobody can fix later. A tailor can shorten a sleeve. A shoulder cannot be moved.

Sleeve. A short sleeve hem should sit about 3 cm above the crease inside the elbow with the arm hanging. If it touches the crease, the shirt is a size up. A long sleeve cuff should close at the wrist bone, with about 1 cm of cuff still showing when the arms reach forward over a desk.

Collar. One finger should slide in at the front of a buttoned collar. Two fingers means it will gap under a tie and rub when the child looks down. A collar that pinches gets unbuttoned at 10am and never goes back.

Body. Pinch the fabric at the side seam. You should hold about 4 cm. At 6 cm or more there is too much shirt and it bunches under a jersey. The hem should stay tucked when the child raises both arms.

Body point	How to check it	Sign it is wrong
Shoulder	Seam on the point of the shoulder	Inside the point, or hanging past it
Short sleeve	Hem 3 cm above the elbow crease	Grips the arm, or reaches the crease
Long sleeve	Cuff at the wrist bone, 1 cm shows when reaching	Above the wrist, or over the hand
Collar	One finger fits, buttoned	Pinches, will not close, or gaps
Body	4 cm pinch at the side seam	Under 2 cm, or over 6 cm of slack

Our shirts run in age bands: 3 to 4 years, 7 to 8, 11 to 12, 13 to 15 and 16. A tall Grade 4 in an 11 to 12 shirt is normal, and so is a small 13 year old in the same size. Measure the sleeve from the point of the shoulder to the wrist bone, write it down, and compare it with our school uniform size guide before you order.

Measure four things at home with a soft tape:

• Shoulder point to shoulder point across the back.
• Shoulder point to wrist bone, with the arm hanging.
• Neck around the collar, with one finger of room.
• Chest around the widest part, tape level.

Buy for the shoulder and the collar. Sleeve length can be fixed with a needle in ten minutes. A shoulder cannot be fixed at all.

Short Sleeve in Summer, Long Sleeve in Winter

South Africa does not have one winter. Johannesburg and Pretoria get dry cold mornings and mild afternoons. Durban gets humidity that makes a heavy shirt feel like a plastic packet by lunchtime. Cape Town gets rain and wind that find every gap in a collar.

A Short Sleeve Shirt at R93.99 earns its place from late January to March and again from October. Air moves at the elbow, there is nothing to push up, and it layers under a jersey without a bunched sleeve digging into the armpit. The trade-off is bare forearms in July and sun on the arms at break in November.

A Long Sleeve School Shirt at R99.00 is the winter shirt for the Highveld. A buttoned cuff does not ride up while a child writes, and the fabric traps a thin layer of warm air under a jersey. The trade-off is that the cuff wears through first, and a sleeve that is too long ends up in the ink pot.

Fabric weight matters as much as sleeve length. School shirts are usually polycotton, either 65/35 or a cotton-rich blend between 60/40 and 80/20 cotton to polyester, as this care guide explains. Kentaur's wash guidance puts the practical difference plainly: more cotton means a softer shirt that takes longer to dry. In a humid coastal town that decides how many shirts you need. On the Highveld in June it decides whether the shirt is dry by Monday.

Condition	Short sleeve	Long sleeve
Classroom at 30C	Air moves at the elbow	Warmer than needed, sleeves get pushed up
Dry winter morning	Cold forearms, jersey needed	Holds warm air under a jersey
Coastal humidity	Less fabric on the skin	Sticks to the arms by mid morning
Under a blazer	Forearm shows without the jacket	Correct look, cuff shows at the wrist
Desk work	No sleeve to drag	Fine if the cuff fits
Wear life	No cuff to fray	Cuff and elbow go first

If the choice is still open, our summer uniform guide covers heat in more detail, and the winter uniform guide covers the cold terms.

A short sleeve is a warm-weather shirt that survives a cold morning. A long sleeve is a cold-weather shirt that survives a hot afternoon only with the sleeves rolled, which stretches the cuff.

Layering Without Bulk, and the Two Shirt Compromise

Bulk comes from the body of the shirt plus the body of the jersey. It almost never comes from the sleeve. That is why a child in an oversized short sleeve under a jersey looks bulkier than a child in a fitted long sleeve under the same jersey.

• The shirt should allow a 4 cm pinch at the side seam, no more.
• The jersey should fit over the shirt with room to reach forward, and no tighter.
• The blazer is the layer that gets bought a size up, if anything does.

Most families land on a split rather than one cut for everything. Three short sleeve shirts and two long sleeve shirts covers a Highveld year for one child: short sleeves carry Terms 1 and 4, long sleeves carry the back of Term 2 and all of Term 3.

The bottom half changes how the shirt sits. A shirt tucked into trousers stays tucked through a day of sitting, while one tucked into a pleated skirt rides up on stairs, so hem length matters more. For the cold terms, the Grey School Pants at R151.99 carry the uniform. For Terms 1 and 4 the Grey School Skirt 2 Pleat at R117.99 does the same job with less fabric.

The detail that decides whether the outfit looks right is at the ankle. A crisp white shirt over socks that have gone thin and grey undoes the shirt entirely, which is why the White School Socks Girls Anklet at R24.99 sit on the same shelf.

Buy the shirt for the body your child has, the jersey for the shirt, and the blazer for the jersey. Reverse that order and every layer fights the one underneath.

What Wears Out First, and What to Check in the Shop

A school shirt fails in a predictable order. The collar fold line goes first, because it rubs the neck all day. Then the cuff on a long sleeve, on the inside edge where it touches the desk. Then the placket buttonholes, which stretch from being pulled open rather than unbuttoned. Then the underarm. The elbow and hem come last.

Three checks take under a minute:

• Button and unbutton the top button three times. If the hole stretches on the third try, it will not last a term.
• Pull gently on the placket and the shoulder seam. Stitching should be tight and free of loose ends.
• Turn it inside out. Overlocked seams and a spare button mean someone thought about the parts you cannot see.

The same checks apply to a hand-me-down, which is where many families save real money. A second-hand shirt is fine if the collar stand still holds its shape, and this uniform exchange guide shows how to sort donations so the good ones get worn.

Turn the shirt inside out before you buy it. The outside is advertising. The inside is what you are paying for.

Which Shirt for Which Term?

The published 2026 term dates put the year at 200 school days across four terms.

Term	2026 dates	Shirt call	Why
Term 1	14 January to 27 March	Short sleeve, jersey for mornings	Peak heat and humidity
Term 2	8 April to 26 June	Both, long sleeve from June	Starts warm, ends cold
Term 3	21 July to 23 September	Long sleeve	Coldest mornings, wind on the playground
Term 4	6 October to 11 December	Short sleeve	Heat returns, long sitting in exams

Term 2 is where parents get caught. It starts warm in April and ends cold at the end of June, so a child with only short sleeves spends the last three weeks in a jersey over a summer shirt. One long sleeve bought in May fixes that without a full winter set.

If June arrives with only short sleeves in the drawer:

• One long sleeve in the right size beats a jersey over a summer shirt.
• Check the cuff length before Term 3 starts, not after.
• Pass the outgrown short sleeves down rather than keeping them for next year.

The gap between the two cuts is small, which is why the decision should be about weather and wear rather than saving money:

Item	Price	Cost per wear at 40 wears
Short Sleeve Shirt	R93.99	R2.35
Long Sleeve School Shirt	R99.00	R2.48
Difference per shirt	R5.01	13 cents
Three short plus two long	R479.97	About R2.40 blended

Run those numbers against a replacement and the case gets stronger. A shirt bought a size up that has to be replaced in Term 2 costs R93.99 twice, which is R187.98 for one shirt that never fitted. Buying correctly costs R93.99 once. With uniform costs reported as a growing strain on family budgets, that R94 error gets more expensive every January.

Two shirts in the right size beat four in the wrong one. The wrong size gets replaced, and the replacement costs more than the upgrade would have.

How Do You Keep a White School Shirt White?

White shirts go yellow because of what stays in the fabric, not because of the wash: body oil at the collar, deodorant at the underarm, detergent residue and fabric softener. Fix those four and a polycotton shirt holds its colour for years.

• Wash whites together, separate from colours, every time.
• Use oxygen bleach rather than chlorine, which can yellow a shirt that is not fully rinsed, as the Kentaur guidance notes.
• Skip fabric softener. It builds up on the fibre and dulls white cloth.
• Rub liquid detergent into the collar and cuffs five minutes before washing.
• Do not over-dry. Polycotton taken out slightly damp and hung up loses most creases.

Ink is the other white shirt problem, and it is almost always a pen left in a blazer pocket. Tide's ink stain guide sets the order that works: test a hidden patch, blot rather than rub, flush with cold water, then pretreat before washing. Rubbing spreads ink from a dot into a patch. Earth Breeze's polyester washing tips cover the heat settings that keep a blend from going shiny.

Problem	Cause	Treatment
Grey collar line	Body oil and detergent residue	Detergent rubbed in before the wash
Yellow underarms	Deodorant set into the fibre	Oxygen bleach soak, no ironing until clear
Ballpoint ink	Pen left in a blazer pocket	Colourfast test, blot, cold flush, pretreat
Grey cast overall	Softener build-up, over-drying	No softener, line dry, oxygen bleach monthly
Set creases	Tumble dried too hot	Remove damp, hang, iron on low

The full routine, including sweat marks and grass, is in our school uniform washing guide.

White is not a colour you buy. It is a habit you keep, one collar rub at a time.

Frequently Asked Questions

Is a short sleeve shirt too cold under a jersey in winter?

No, if the jersey fits and the shirt fits. The arms are the only exposed part and the jersey covers them. The real problem in July is the gap at the wrist when a child writes with cold hands. For a Highveld winter, a long sleeve is the better call.

Can my child wear a long sleeve shirt in summer?

Only if the school allows it. A long sleeve in February is warm, and most children push the sleeves up, which stretches the cuff. If your child burns easily or the school requires long sleeves all year, buy the correct size and keep the cuffs buttoned. Sun protection is a fair reason to bend the seasonal rule.

How many school shirts does one child need?

Five works for most families: one per school day, washed over the weekend, plus a spare for the midweek wash. Split them by term instead of buying one cut. Three short and two long covers a Highveld year and costs R479.97 at current prices.

Do school shirts shrink in the wash?

Polycotton shrinks far less than pure cotton, but a hot wash and a hot tumble dry will still pull a shirt in, mostly in the length. Wash at 40C, use the lowest dryer setting, and hang while slightly damp. Do not buy a size up hoping it shrinks into place, because it will not shrink evenly.

What shirt size should I buy for a Grade 1 child?

Start with the 7 to 8 years band, then check the shoulder seam and the collar. Plenty of six year olds fit a smaller band in the body but need a longer sleeve, which is a sign to move up.

Unsure between two sizes? Order one of each and keep the one that fits at the shoulder. That costs less than replacing a full set in March. Both cuts are in stock now.
