They're not so different from those leggings with the lace around the bottom....which might be a safer bet. But they could work for you....you'd have to be careful about the skirt being totally opaque.
Evans do something like this?! I haven't gone near an Evans in years (fed up with the crap quality and styling). I shall have to have a look.
Mmmm...£5 v £15...OTOH, silk v nylon...
I tried 3/4 length leggings. Not a good look when you're a big momma. Well, that's what I thought, but I jsut don't know - is it that it's something new and therefore I'm not used to it so it looks wrong? I wish there was someone I could ask, but it's such a "does my bum look big in this" question!
