Alice and Olivia black puff sleeve blouse top. Slightly cropped— I have a longer torso (see second photo for fit). I bought it at a special event at the NYC Alice and Olivia showroom as shown on the tag so it is very limited edition. It doesn’t have a size but I would say it fits a small-medium. The shirt definitely has some spandex/elastane material as it is stretchy and sturdy. For reference I have a size 27 waist and it fit me well when I was fluctuating in weight in between a waist size 25-28. Perfect for a night out and events! Can be dressed up or dressed down. Open to offers!
