Try some women's shorts! They might have the fit you need, and I don't see much difference in how they're made, tell the folks at the shop that you and your wife or GF wear the same size if they really wanna know.... Izumi's have this huge pad, I don't like them, I have some Sugoi's I do like, the pad's a lot thinner and doesn't seem to get sticky etc., - there are a lot of different types of chamois and "chamois" out there, also, you might consider some you can't get there, like Castelli's etc., shorts made for the european market might fit your build better, it sounds like you have thinner legs than most.
