Teenage football shirt sizing? Any experts?

[whydontpoo]

Just a thought as I muse what size to buy my son.

He's in adult size- small often too small, medium often too big depending on shop!

With the replica football shirts, any idea whether they come generous or not. He's 15 and 6ft but really skinny!

Any help would be welcome as I've never bought one before 😐

Depends what brand the replica shirt is - often Nike so you can go by the size guide on their website. IME they are often narrow and long.

This is nike. Thank you. Thing is with any other clothes I'd buy medium and think he'll grow into it.. I guess these have a shelf life though due to the ridiculous need to change every season I believe so I want to get the best fit.

Recently bought lots of new clothes for him in medium that swamped him.
