Trousers for slim but long leg

[Lionnose]

My 2 yr old doesn’t seem to fit most trousers. Any suggestions of shops that seem to fit slim but longer leg? He’s wearing a 1.5-2yrs for length but so far can’t find any that fit his waist, they all fall down.

My DD has this problem and I find H&M the best.

YY to H&M, and GAP too. Is he out of nappies?

Look for trousers with a working drawstring. I remember Next and Asda being good, look for the cheaper styles they tend to be economical on fabric!

Thank you! We have tried Asda. Which was not good unfortunately. I have just ordered some H&M & Next. Thanks for the suggestions. He is out of nappies. The nappy definitely helped keep them up!
