Every time my son gets any sort of new bottoms they tend to be too big around the waist, even the ones with the buttons inside to make the waist smaller don't always help too much.
Anyway when we got his uniform we managed to get trousers that are a fully elasticated waist, no buttons to adjust the waist and no hook and zip, they just pull on.
We purposely looked for that type and found them in Asda.
They used to do shorts that were the same, but unfortunately they didn't have them anymore.
Does anyone know anywhere I could get school shorts with this type of waist? They need to be grey and my son is 5. (I did think maybe I could just get some of his trousers shortened as he has enough, but I would prefer to get shorts if possible).
