Agent Provocateur Joan Lightweight Brief In Nude With Black Trim. Cause a stir this season in delicate yet decadent Joan. This striking brief is made from mink-coloured microfibre in an ultra-fine, lightweight finish, trimmed with soft black cire elastic in a wet-look finish to contrast the nude base. The black elastic straps sweep across the base and cross over in a striking, graphic effect, with a cutaway effect at both the front and rear for a mischievous touch. The smoothline finish makes the Joan lingerie set a great choice to wear under tight clothing.
