I am 5'2", 120-125 lbs, and wear size 6 jeans, so size small would typically fit.  But with these drapey skirts, I worry about them clinging to and accentuating my thigh bulges.  So, I ended up getting medium.  I'm so glad I did, because this definitely runs small, and size small would have been way too tight. I wear it pulled up to my waist and rolled over all the way, and the length is good, almost to the floor.

I chose color Ff8 Multi, which is a bright and gorgeous print. But, with any light shining on me, the silhouette of my legs is clearly visible through the fabric.  If I had bought this skirt for work or slightly dressier occasions, a slip would be a necessity.  However, I plan to wear this only for very casual use, so I'm not terribly worried about it.  The material is thin, smooth, has a nice drape and movement. I had a similar long, casual, easy skirt last summer and wore the heck out of it, so I'm glad to have another option in my closet.
