Rare early 1966 Biba polka dot blue cotton drill mini dress.
Classic sleeveless design with racer back armholes, double pointed collar with pockets either side, button down front with darted body giving an A-line cut. This predates the woven label so simply has a small size label in the neckline. 
This has a couple of small marks in places ( see photos ) but they are not that noticeable when worn. This is a rare early piece of Biba history which rarely come up. 
Perfect for any collocation or collector of rare fashion pieces.
