I am only 5.1" and often have a real problem with tights rolling on the waist. I have recently tried Snag tights and although they don't roll, I am not impressed at the fit. I thought I'd try Heist but the low wasted navy tights have been out of stock for ages. Will I regret buying the high wasted? I'm thinking they'll probably reach my armpits and I'll be back to square one, having paid £22 for a pair of tights!
