I may be a little AIBU because I'm posting here for traffic, but hoping someone with a similar shape child can help me.
My son starts school in September. He is 4.5 yo but is very skinny and very very tall (98th centile for height).
This means that for trouser length he really needs age 5 or even age 6, the problem is that he has the waist size of a 3 year old.
His legs are also very slim.
I am despairing of how to get school trousers to fit him tbh. All the ones we've tried so far he needs age 5or 6 for them to be long enough, but that means they are vast at the waist, you could literally fit two of him into them. Even "slim fit" trousers have been no better, those are generally a better fit on the legs and bottom but still far far too big at the waist.
I managed to get a pair of girls longer length age 5 to sort of fit by cinching them in with the elastic and buttons at the waist but that made them really bunched up all across the back and it didn't look comfortable at all.
Can anyone offer suggestions of shops that sell school trousers for skinny beanpole kids?
