Very comfortable, stretches to fit my growing bust (6 mos pregnant) and the thin lining provides some shape and privacy.  I was a 34E before pregnancy (likely G now) and ordered the XL based on the sizing comments, but think a L would have fit better around the torso and still left enough room in the cups.  I'm currently wearing them on the smallest hook and find them a bit large, but they shrink again after being washed.
