Most school polo shirts go grey by February. That happens in September, not in the wash.

Why Fabric Weight Is Everything
Lightweight polo shirts below 160gsm pill after around 10 machine washes. The number to look for is grams per square metre, printed on the care label or listed in the online product description. A 180gsm shirt costs roughly the same as a 150gsm one and outlasts it by at least a full term.
Poly-cotton blends resist shrinkage and keep their collar shape after tumble drying. Pure cotton feels softer but the collar goes flat quickly. For children who play on the floor, pull jumpers on and off 20 times a day, and occasionally do PE in their uniform, the blend wins by March.
Sizing: Buy One Size Up
UK school uniform brands run small. If your child wears age 6 in standard clothes, try a 6-7 or 7-8 in school polo shirts. The extra length at the back matters because polo shirts come untucked constantly throughout the day. Buying exact-fit in September means a tight collar by January.
A multipack across two sizes gives you flexibility mid-year. The Amazon Essentials Boys' School Polo Shirt 2-Pack is available in multiple colour options to match most UK state school requirements, and splitting between two sizes keeps the cost low.
Washing to Preserve Colour
White school polo shirts turn grey for one reason: washing at 60°C in a mixed load with adult clothes. The correct cycle is 40°C with other school whites only. A cold rinse before the main wash removes most grass and mud without setting the stain. Fabric softener weakens poly-cotton fibres over a term, so skip it or use half the recommended dose.
For girls, the Amazon Essentials Girls' Uniform Polo Shirt 5-Pack comes in white, sky blue, and navy for under £20 delivered. Five shirts washed twice a week covers a full school week with room for slow-drying days.

FAQ
What is the best fabric for kids school polo shirts?
A 65/35 poly-cotton blend at 180 to 200gsm is the most practical choice for daily school wear. It resists shrinkage, holds its collar shape after tumble drying, and survives repeated 40°C machine washes better than 100% cotton.
Should I buy school polo shirts a size bigger?
Yes. UK school uniform brands run small, and children grow an average of 5 to 7cm per year. Buying one size up at the start of term means the shirt still fits properly at Easter and beyond, rather than pulling tight across the shoulders by Christmas.
Why do white school polo shirts go grey?
The main cause is washing at 60°C in a mixed load with adult or non-white items. Wash school whites separately at 40°C. Avoid fabric softener, which dull the weave and weakens fibres over the course of a term.
How many polo shirts does a child need for school?
Three covers a week if you wash every other day. Five gives a buffer for slow-drying winter days. A 5-pack washed twice a week means your child always has a dry, clean shirt ready without a morning scramble.
Are branded school polo shirts worth the extra cost?
For standard polo shirts without a school logo, no. Non-branded 65/35 poly-cotton shirts from Fruit of the Loom or Amazon Essentials match supermarket-branded options on durability at a lower price per shirt. Only branded options make sense when the school requires a specific logo.
