LOVE these scrubs, these are by far the most comfortable workers scrubs. If you bend, move and do a ton of upper body movement in your area, these are the perfect brand! I purchased a medium according to the size format, I am a medium, but when I got them they were TOO big. I would recommend going down a size from what they suggest. I am a 36 bust, 29 waist , 40 butt and smalls fit perfect! Enjoi!
