Hmmm, well I normally wear a size 8 in jeans but when I went to American Eagle to buy jeans, I couldn't figure out what size I needed cause their sizes were in the 20's and 30's. I found a really nice associate to help me and the size I needed ended up being a 31 so my guess would be probably about a 6. but since your hips are normally bigger than your waist and that is where low-rise would sit then you might want to go a size bigger than you normally wear. Just try them on until you find the size that you feel most comfortable in.
