Looks like reconstructed old sweatshirts!
I truly cannot understand the great reviews on this dress!  i purchased in both a sp and a mp.  i am 5'2" 120#.  the mp fit perfectly.  i definitely wouldn't keep it though because it looks like someone sewed a bunch of old sweatshirts together.  it's not super soft, coarse on the inside, and feels old.  the back is longer than the front, it just looks like something my daughter would make in sewing class out of scraps.  even with leggings and great boots, it looks worn.
