I've got quite a few tops/tunics that would be nice with leggings, but the only pair I own (control ones from Avon) are really tight round the waist. I've got big thighs but a decent waist so don't understand why they're so uncomfortable? I don't want to spend a fortune (maybe £15-£20 a pair at the most??) but am so clueless I'm wondering whether to get maternity ones just to get a bit of breathing space?!? Any thoughts would be very welcome...
