As a person who wears scrubs for work I can say that Uniforms By Karen has everything you might need. They recently had a sale that I decided to check out.
The place is a bit crowded with racks, so its hard to maneuver around. The women here seem to be grumpy, but helpful. They carry every color and pattern of scrub top and bottom that you could imagine. They carry drawstring bottoms, which are my preference over the elastic band ones. The fit of the scrubs are true to size. They are pricey, a top usually goes for $40, maybe $20 on sale. The bottoms cost the same. You can get sets for $50. They also carry shoes, which are around $95 to $130. There are other health care accessories and stethoscopes.
This is a great place to stock up on any scrubs you might need, though they are pricey.
