Inspired by antique “skeleton keys,” jewelry featuring key pendants has hit the forefront of fashion and style over the past few years. The dainty antique details add a trendy, feminine touch to any outfit. Perfect with a pair of jeans and a simple t-shirt or a cocktail dress, skeleton key necklaces are just as versatile as their namesakes.
