Bought for cycling but happened to receive it right before a trip to Vail, Colorado. Wore it in Vail and was shocked by how many compliments I received. It is gorgeous! I am age 61, 5'6", 158 lb, 34D, athletic build, and short-waisted. I wear a M-L or 10-12 in USA sizes and XL in Cycology short sleeve jerseys. I wear XXL (yikes!) in this base layer. My main goal in cycling clothes is to be SEEN after having a serious bike wreck. I ride a daily (weather permitting) 10-mile loop for exercise and find that base layers work fine in lieu of zippered jerseys.I hope this review helps.

I'm normally a S or XS-5'6", 117#-and the top was very snug. I decided to return it and order a M.

I originally bought a medium, wanting a less than performance fit. I am 5’4/-120lbs/not curvy. I ended up with a large which fits great and is not at all baggy. I would advise sizing up even if wanting a performance fit. I usually wear a small in most tops.
