Where can I buy slim fitting trousers for my 10yr old son?

[doran]

I am fed up with my son looking like a bag of old washing. I can get slim fit school trousers, but fail miserably to get him casual trousers that actually fit. M&S (etc) do adjustable waists, but I'm having to gather in over 3 inches.

Any ideas who sells trousers to fit a tall, slim lad.

Thanks a million.

BHS do them, and Next. My son is 140 cm and 4 st 8 lb so I know what it's like!

I get trousers from debenhams designers, ie conran/red herring that type of thing, but wait for the sales. The trend seems to be generally for wider fitting clothes

Yep Debenhams are slim waist but tend to be quite short so may need a size bigger.
