I wear a 4-6 or a small in most women's clothing brands and I know Amazon just threw their own sizing information in as a place holder but it is so far off, they should really remove it.  I ordered a small and it is miniscule.  I didn't even try it on because it would have been physically impossible (the skirt laid flat was half the width of my average-sized hips).  I really loved the peach color though and it seemed like sturdy enough construction for the price so I will be ordering a medium (or maybe even a large) and hoping it will fit!
