I ordered this in a large as I remember. It was way too big for me. I should have gotten a small...but,nevertheless, it's a beautiful top and I may reorder at some point :-) You can't go wrong with their products!
I usually wear a size medium in Novica sizing. This S/M that I purchased is a perfect fit. I washed it on the gentle cycle without using the spin cycle, then air dried it. The colorful design is beautiful.
