NWOT ELLEN WEAVER White Cover Up or Tunic Cotton Size M/L

NWOT Ellen Weaver Beach Coverup or Tunic All white light crinkle cotton with lace detail on edges Deep v Neck front Slits on sides 3/4 sleeves Size:. This is marked an XL. I do not feel this is an XL. I tried it on and I'm a large and this was snug at the hips. If this is to be worn as a tunic or coverup it should be loose and flowy, so I'm marking this as Medium- Large.  Please check measurements.  I've given a lot of them so you can make sure it will fit like you want. Measurements are approximate: 22" Pit to pit, 31" shoulder to hem, 42" waist around, 45" hips around 6
