I have a very boyish figure, no hips, hardly any bottom, and so slender I usually have to stick to the Junior's department instead of Misses' (though I wear a size 3 or 5, not a 00!). I am just thrilled to find pants that aren't too baggy in the hips, and don't have a super-low waist which I hate!
I love SO brand jeans -- I find them at Kohl's, usually on sale for $20! The style I buy (I think it's just their regular flares) fits about an inch below my belly button, has a smaller flare than a lot of Junior's flared jeans (large flares overwhelm my slender figure), and even makes me look like I have a bottom!
When I wore them home for Christmas, my mom was amazed that it looked like I actually had some curves! lol
