i suggest frever 21. there highwaisted jeans are ONLY $12 and you would be a size 24 or 25 or 26. there regular jeans are ONLY $10. you would be the same sizes

I was say you would be a size 1ish. It depends on the place.

I'm a size 12 Slim in Old navy kids jeans. I found nice shorts and nice jeggings at Garage. Size 000 so maybe try a 00 or 0?
