Side cut-out Midi dress

NWOT: I bought this from one of those FB ads and it was supposed to be a 12 (L) but fits more like a 8-10. The fabric is a poly-cotton blend (65/35). It does not have a label; it's a very light pink with blue feather-like design. V-neck with a drop style waist. It's a casual, comfortable and fun look; summery. (Just not for me!)
