Product description from Net-A-Porter, where it last sold (now out of stock):
Nodding to classic styles from the ’70s, Alessandra Rich’s polka-dot dress is as playful as it is elegant. It’s been made in Italy from lightweight silk crepe de chine with puffed mutton sleeves and a drop-waist pleated skirt. Sweep up your hair to showcase the retro buttons along the high neckline.
