I first ordered a medium and this skirt was super duper tight.  from the side I looked like I was wearing spandex pants.  I like it to look like a skirt from all angles so I returned it and got the large which is still surprisingly tight... and normally I'm a size 5 in juniors.  But the large is cute enough.  I really like how the top fits... no bulk and very smooth.  It definitely hugs my booty but not in a scandalous way like the medium did.
