Where can I buy tops that cover my arse?

[StuffedFullOfNothing]

Where can I get decent quality, long-line tops that won't lose their shape? I want some that come right down over my bum.

TIA

I got a few long tops in cotton from Cotswold sports /outdoorsie type shop. Pretty pattern, v neck 3/4sleeves slight gather at bust and iron up easily.

or try gap and oasis - they have short cotton dresses which would look nice over jeans / trousers/ leggings.

celtic sheepskin do some.
