Agent Provocateur's 'Robyn' briefs have an intricate construction that took over a year to perfect. This hipster style is made from plum stretch-satin and has keyhole cutouts on both sides of the low-rise waistline. They're lined with delicate French Leavers lace and have flattering straps that sit just above your hips to elongate your torso. Wear them with the matching bra.
