The Outnet for instance. Any good? Also isn't there another one called something like (don't laugh) squoosh.com? Ahem.
Anyway, am looking for some high waisted, wide legged navy trousers, and everything on the highstreet is either viscose or polyester 
I want these trousers to be good quality and to last as part of my staple wardrobe. So don't mind forking out within reason.
Thanks!
