I have this really awkward lower body shape going on, and I like the "supported" feel of proper riding tights or breeches. I've used Kerrits riding leggings but I don't like them. They're too much like normal leggings so my legs appear to "jiggle" more than they would if I wore tights or breeches. It does not compliment my position.
I've found cheap breeches before. Stores that aren't "brand name" like Dover, Bevals, etc usually have some really cheap ones laying around. We have a HUGE warehouse of horse stuff around here...You can buy $200 white jods and $10 used breeches in the same store!
