This is a playful, casual to slightly dressy piece, good for apres-climb, rest days or even work days. The fit is clean and modest, though a bit roomy in the chest, and is a good choice if you plan to (or accidentally) overindulge on a meal or two. It goes well with tights or jeans or a long, simple skirt. Because of the fabric, it can get a bit clingy at times, so you may need some anti-static/cling spray after a wash. This is a great top for warm days or to layer under a shawl or hoodie. Fits true to size, but is intended to be a bit more billowy than form-fitting. I'm 5'3", 140lbs and wear a medium, as I do with most OR tops.
