There may be no answer, but on the off chance.
About 6 months ago, I bought a pair of ladies tight fitting stretch jeans. Fits perfectly every where except the waist, which is about an inch too wide so the damn thing keeps slipping off me as I walk along and I have to keep pulling me trousers up every 15 minutes, which is a bit embarrassing.
When I tried it on at the store, I didn't really notice that the waist was slightly too big, but it has become more obvious now that I have started to wear it.
Any great ideas on how to stop the jeans slipping off that won't compromise the look of the jeans? I don't really want to wear a belt and I certainly don't want to put on weight just to fit into the jeans!
