I've started working out more and want to get a few more nice outfits - some leggings and a vest top. I have a lot of cheap stuff which I absolutely boil in. As I'm a few stone overweight I get really sweaty, so I'd like some good quality fabrics to keep me cool. Size 18 and large of bum/thighs on bottom and size 16 on top. Can anyone recommend anything? I'm tempted by Sweaty Betty but it seems incredibly expensive. Ideally looking for 3 outfits so I don't have to keep washing them in between workouts
