This black silk-blend Gilded Arch thong is a key piece in Coco de Mer's capsule collection with the Victoria & Albert museum. It's crafted with a black and gold Art Deco-inspired arch lace – lifted from the aforementioned institute's archives – with a high-rise waist that is shaped with a cut-out back panel, then secures with a hook clasp. Style with the label's coordinating bra to tap the bygone-era aesthetic.
