I was surprised at the quality this set for the price...in a very good way.  I'm 5'7" / 130 lbs. I ordered an XS which fits perfect after an initial wash and dry.  I bought the navy set which is true to the color swatch.  I love the tie at the back of the shirt - such a simple thing that makes the scrubs look much more flattering.  For this price I plan to buy a few more sets in other colors. I'm completely happy with the purchase.
