I was excited to see Koi release a form fitting bottoms. Especially with double cargo pockets! I wear a XS in the Lindsey 701's. So, I order the Lindsey Slim in XS. Boy was there a HUGE difference in sizes. When I received them, I opened the package and I knew they were too small. I didn't even bother trying them on. Sent them back. So, if you plan on going with these, I suggest going up in size, or try them on in a store, then order.
