Ditto on talking to customer service at Team Estrogen. They are extremely helpful.

I also don't love Pearl Izumi. I have just one pair of shorts, and I like the fabric but I don't like the big chamois either and they seem to cut for a taller person than I am. I really like the pair of Shebeest I have (though they are not really available now) and also like Giordana.

If you can at least try them on locally, that will give you an idea of size, even if you don't find your preferred brand.
