I guess it could be argued that any chunky choker type necklace is a corset … of sorts. Lorette Colé Duprat Is definitely taking her inspiration for that form, using large silver coloured beads and a laced up look. The piece can be worn front or back facing. (The beads may be plated sterling silver; it’s unclear from the description, which says “full silver.”)
This is priced at £463.
