I love Born Primitive products, especially their sports bras. I have a couple pairs of their leggings as well, including these capris. While I find that their bottoms are great quality and very flattering, I do find that they seem to be made more for a "junior" physique rather than an athletic/muscular physique. I'm 5'5", approx. 150#, muscular build. Everything I wear is a size 6 or S/M. I ordered these in medium and they are TIGHT. Almost uncomfortably so, but I'm keeping them and I will wear them. From now on, however, I will have to order bottoms from BP in a large.
