I bought these scrubs for work in my chiropractic office.  I am 5'7" and 140 lbs.  The small fits me great. The pants are the perfect length too.  I love the mock wrap style like this.  I now have 3 sets of these scrubs.  On my pink set, I first received a Small top and a Medium bottom.  I called and Marcus Uniforms emailed me a return label.  I returned the package to the UPS guy that was here dropping off a different item (I buy a lot of stuff online).  Shipping is fast.  Nothing to really complain about with these scrubs, besides the threads that are always dangling off somewhere.  The fabric softens up quite a bit after two washes. I would purchase again.
