Your Child's First Proper Football Shirt: A Parent's Guide
A child's first proper football shirt should fit room to grow into, suit how they'll actually wear it (kickabouts, school, telly nights), and be looked after properly so it lasts. Here's how to get the size right, why a surprise team can be a good way in, and how to keep the shirt in good shape.

Why the first shirt matters
For a lot of kids, a football shirt is the first piece of clothing that feels like it belongs to them rather than being picked by a parent. It's a costume, a comfort item and a conversation starter all at once. Getting it right early on — a shirt that fits, that they actually want to wear, that doesn't fall apart after a few washes — makes it much more likely to become a favourite rather than something that sits in a drawer.
There's also no rule that says the first shirt has to be from the team you support, or even a team you've chosen at all. Plenty of parents use a child's first shirt as an open door into the game generally, rather than locking them into a single club before they've had the chance to form their own opinions.
Getting kids' football shirt sizing right
Kids grow fast, and a shirt bought too close a fit will be outgrown within a season. Kids football box sizes run XS (5-6 years), S (6-8), M (8-10), L (10-12), XL (12-14) and 2XL (14-16), which is a useful guide even if you're buying from elsewhere: match the band to your child's current age and, if they're tall for their age or you want it to last two seasons, size up to the next band rather than down.
A few practical sizing tips
- Measure chest and length against a shirt that already fits well, rather than relying on age alone.
- If your child plays sport in it, a slightly looser fit is more comfortable for movement than a snug one.
- For a shirt that's mostly for watching matches or everyday wear, a size up means more wear out of it before they outgrow it.
Why a surprise shirt can be the right first shirt
Every kids mystery football shirt box contains one shirt chosen at random from any team, any year, club or country — you'll never get a pre-match or training shirt, and every order comes with an information card explaining the team your child received. For a child who hasn't picked a team yet, that's a genuinely good way to start: instead of a parent guessing which club will stick, the shirt itself can spark the interest. A surprise shirt from a club or country they'd never heard of often becomes the start of a story — asking where the team is from, what the badge means, who plays for them — rather than the end of one.
It also takes the pressure off picking "correctly". A shirt chosen for a child, rather than by them, removes the risk of buying into a team that turns out to be a passing phase, and the information card gives you something to talk about together when it arrives.
Looking after a kids' football shirt
Shirts worn for play as well as for best need a bit more care than an adult replica that's mostly for show.
Washing
Wash inside out on a cool, gentle cycle to protect printed numbers and badges, and avoid tumble drying, which can crack printed detail and shrink synthetic fabric over time. Air drying flat or on a hanger keeps the shape better.
Everyday wear
If the shirt is going to be worn for actual football as well as casual wear, having a second, older shirt for muddy kickabouts means the newer one stays in better condition for school discos, family photos and match days on the sofa.
Growing into it
A shirt bought a size up can be rolled at the sleeves or simply worn a bit baggy for the first few months — most kids don't mind, and it buys you another year or two of wear before the next size is needed.
What "proper" actually means
Parents often use "proper" to mean a shirt that's a step up from a supermarket football top: genuinely authentic, officially licensed and new, rather than an unbranded print. That distinction matters more than it might seem, because a licensed shirt carries the real club or country crest and matches the design actually worn by the team, which is usually what makes it feel special to a child rather than just another football-shaped t-shirt. Every mystery shirt box is 100% authentic, officially licensed and new, with tags, so whichever team your child receives, the shirt itself meets that "proper" standard.
That's worth knowing before you buy anything described as a football shirt online, since not everything sold that way is genuinely licensed. A proper shirt should carry the club or country's actual badge and sponsor detail as worn, not a generic design with a team name printed on.
Choosing the right moment to buy
There's no single "correct" age to buy a child's first proper shirt, but a few natural moments tend to work well: the start of a new football season, a birthday, after a child has started asking questions about the game, or simply once they've shown an interest in watching it on television or playing at school. Buying before a child has shown any interest at all can mean the shirt sits unworn, so following their lead rather than a calendar date usually gets more use out of it.
If your child already follows a specific team closely, a shirt from that club is the obvious choice. If they don't yet, there's no need to wait until they do — a surprise shirt can be the thing that gets them there in the first place, rather than something you buy only once the interest already exists.
Making it a moment
However you choose the shirt, the unwrapping or unboxing is often what a child remembers most: the surprise, the first time they put it on, the first photo in it. With a mystery box, that moment comes with a bit of extra anticipation, since nobody — parent included — knows which team is inside until the information card is read. For a child just getting into football, that can be as exciting as the shirt itself. Reading the information card together, looking up the team's colours or home ground, and letting your child decide how they feel about their new team all turn a single purchase into a small ritual, rather than just another parcel arriving at the door.
FAQs
What size football shirt should I buy for my child?
Match their current age to the nearest size band — XS (5-6), S (6-8), M (8-10), L (10-12), XL (12-14) or 2XL (14-16) — and size up if they're tall for their age or you want the shirt to last more than one season.
Can I choose which team my child's mystery shirt will be?
No — every box contains one shirt chosen at random from any team, any year, club or country, and you'll never receive a pre-match or training shirt. An information card explains the team once it arrives.
Is a surprise team a good idea for a child who hasn't picked a favourite yet?
It can be. A random shirt removes the pressure of choosing "correctly" and often sparks curiosity about a club or country the child didn't know before, which can be a natural way into following the sport.
How do I keep a kids' football shirt looking new?
Wash it inside out on a cool, gentle cycle, skip the tumble dryer, and keep an older shirt on hand for muddy kickabouts so the newer one stays in better condition for everyday wear.
