Yup - most of my clothes come from Mango and (to a lesser extent) Zara. The Spanish brands are cut smaller.
Also have some bits from H&M as they do some clothes in size 4/6/xxs.
I've managed to buy a few bits from &Other Stories occasionally too but not many.
The length on trousers I sometimes have to have taken up, depending on the style but thats easy enough for a dry cleaners to do. Makes a difference if the waist position, hip width, sleeve length, neckline etc fit.
