Combining a sweet Peter Pan collar shape with a studded metal collar is, well, jarring. But that was likely the intent of this Louis Vuitton necklace, dubbed the Lock Me Frame Collar.

It’s made of studded gold plated brass, and with dimensions of 16 x 3 cm / 6.3 x 1.2 inches, intended to fit the wearer’s neck quite snugly.

It sells for USD $1,440, in the event your S+M means sweet and metallic.
