I love all of the 100% cotton pants Gap has been making so when I saw these I knew I needed them! I am always a medium petite in Gap as a size 8. I ordered these in a medium petite but I think they run slightly snug (especially if you have larger thighs) so I'm going to return for a large petite because even though they fit, any shrinkage will make them much too snug so if you're at all between sizes.. size up in these. I have the barrel version and these do run smaller than those I would say!
