Agent Provocateur Crotchless Knickers Lorna Ouvert In Black With Pink Trim. The irrepressibly charming Lorna is back, in a freshly reworked design and an improved fit. This naughty black ouvert brief is made from fine net tulle, with baby pink embroidery and seam detail and a tantalising keyhole decoration, topped with bows. At the rear is another cheeky peephole-style cutaway design. Wear with the matching Lorna bra and suspender.
