I have a pair of Joe Rocket riding pants that seem to be an actual size 6, if you want to try them. I bought them for myself, in the size I normally wear for jeans (10), but they turned out to be MUCH smaller! I have a girlfriend your size who tried them on and they fit her great, but she didn't like them because they didn't sit ultra low on the waist.
But they are riding pants, and they are supposed to save you from getting road rash on your butt & lower back, so of course they wouldn't be low cut.
If you want to try them, maybe we can get together for a ride sometime & I'll bring them along. If you like them I only want what I paid for them, which was $35.00 (on sale at New Enough).
They have 6 zippered pockets, and knee & hip armor.
This is me wearing the other pair I bought, which are a little too big but I'm tired of trying to get it right:
