This bra fastens with three rows of double white hooks on white fabric. The exact material of the bra is made of 81% Polyamide 19% Elastane. It is a lovely bra, sexy because it does not cover all the breast and the retail was £27.00. New and unused. Hand wash in cool water, no ironing, no bleach, line dry. I have matching deep shorts and thongs which are listed separately.
