These Lucy tops are one of my all time favorite. I'm sad Lucy is no more and hope The North Face will reincarnate this one (sans the big TNF logo) like they have some of Lucy's other classics. I have this top is several colors and they are great for running, hiking, yoga, and casual wear. They dry quick and fit into the workout wear that doesn't look like workout wear category. I am 5'5" and 135lbs, athletic build and 34C -- small is perfect. One thing I will say about buying this top on Amazon (or any Lucy item) is that for whatever reason many fraudulent sellers, especially from China, seem to target this line. They will provide a bogus tracking # or no tracking # or send a cheap off brand child's shirt. It happened to me 3x! Of course Amazon customer service took care of it immediately. If the price seems too good to be true, it probably is.
