Where do you get clothes for your 16 year old skinny & short boys?

[Grambler]

He's not tall and is stick thin and would be swamped by man size S but most child sizes finish at 14 and he's bigger than that. He lives in man size XS tops which are baggy on him, and aged 14 joggers which are grazing the ankle but the XS ones were too long.

I'm struggling to find jeans - needs to have an adjustable elastic waist as he won't wear a belt.

And pyjamas - where can I find PJs that are a set, both long sleeved and full length bottoms, and a size in between man size S and child size 14/15?

He's more than happy with Asda, Matalan, H&M type stuff but I've run out of ideas! Thanks.

these next pjs go up to age 16.
these underarmour joggers come in age 15-16.
next also sell tshirts in age 15-16
m&s do elasticated waist jeans in 15-16
all the best x

Thanks. Those jeans are pull on though. None of the other M&S jeans state they have an adjustable waist either even though they have the right size.

Next do adjustable waist jeans too

My very skinny teen used to wear stuff from next as they had adjustable waists.

I have tall and skinny but we had success at primark and uniqlo as they do small waist sizes (we were buying long but I think they do different lengths). Think eventually they just have to wear a belt, couple of years ago in Spain we bought one in a leather shop and they cut it to fit him and added extra holes, he is still wearing it now. This year on holiday in Vietnam I had school trousers made for him as there were no other options. I suspect future purchases will involve buying too big and having them adjusted but hopeless for stuff like joggers.
