These jeans (and every pair of bottoms from Vibrant for the matter) are everything. They are super comfortable and stretch beautifully to hug your curves without suffocating you or sagging in different places. I'm planning on buying more in different colors!
I'm 5'5", 105 lbs, and I got a size 1 and it fits perfectly. It's a bit tight, but nothing that does not constitute a size 1 (that's exactly what I wanted, as they do not run small, just fitted!). Highly recommend!
