Women’s size medium long summer dress. Packs great. Has a soft cup built in bra and elastic waist in the front only. It’s a pullover the head dress-no zipper or buttons. No slits. Racer type back. Halter neckline is extremely flattering. There is spandex in the fabric so it does have stretch to it. I am 6’ tall and was around 154 at the time of the picture.
