2X ModCloth dresses with sweetheart neckline, adjustable spaghetti straps, and skater style flared skirt. I believe these are poly material. They have a slight stretch and can fitnsomeone the whole range of 2X size or possibly bigger sizing. They are super comfy! I have sometimes worn without a bra and it worked out although having a bra made me more comfy overall. Colors: One is bright coral, the other navy. Selling as a set! Skirt lands a few inches above the knee on me and I am 5’11 (see photo).
