I've generally found them to run small. I tried the Needle (high-rise skinny) and Flex (mid-rise skinny) and neither quite fit me right so I returned them. Looks like I ordered both in 26 and 27 (I'm usually a 26, sometimes 25). I remember they were all close to the right fit but tighter than I like, but I can't remember which was best - it was inconsistent, because some of their fabrics stretch more.
