I'm usually between S and M for tops (34B chest). I got a small in this and it's very baggy, not like a typical 1/4 zip running top. It's so big that I feel like I need to wear another layer underneath so that cold air doesn't creep in. The material is very soft and stretchy so it's comfortable.
Finally, a half-zip that isn't shaped like an hourglass! I've purchased many half-zips over the years and I love this one the best. I'm 5'5" & 110 lbs, and I purchased an XS - the fit is close but not clingy. I can wear another layer underneath without feeling constricted. The sleeves have a stretchy ribbing at the bottom that double as gloves. This is also an improvement. They actually work as gloves, but push up out of the way easily if not needed.
