Absolutely love this skirt! I am 5'6", 145 lbs, and ordered a medium, per the instructions to size down due to it being a stretchy material. For reference, I am usually between a medium and a large. I wear a large in Retrolicious dresses and tops mostly due to my bust. This skirt fit perfectly and stretched a little bit throughout the day. I definitely had some wiggle room but not to the point where it was gaping or could be pulled down to remove it. This skirt is very comfortable and has pockets. I may need to collect a few more in different colors the next time there's a sale!
