Jo, I forgot to suggest my tips! My sister is always wearing skintight jeans and gave me this tips. After washing them, wear them around the house unfastned for a few hours which will make them easier to get on later. Put a small keyring on the zipper to make it easier to pull. Don't shower immediately before wearing them and instead of lying on the bed or jumping up and down pulling them up, try laying flat on the floor at the top of the stairs - its easier to get up.
I tried it this way and can now get into a pair of my sister's Miss Sixty jeans, which are even smaller and tighter than my skintight Levis! Can hardly breathe but they look amazing!
