I just purchased these leggings in size small, the grey color. I am petite, 5'0 and 120lbs. They fit perfectly and the waistline (as advertised) is very flattering. I can wear them under dresses and skirts without any awkward lines showing underneath. I also plan on wearing these under my climbing pants for cold outdoor excursions. They are super thin, but (so far) feel very warm and cozy.
