Saint Laurent's iconic YSL moniker was created by Ukrainian-French typeface designer Adolphe Mouron Cassandre in December 1961 and makes use of the brand's three initials in a vertical configuration. The discernible emblem accents Saint Laurent's Monogram Celtic belt which has been designed with an ornate antique silver-tone adjustable buckle fastening and features an engraved rear logo, Celtic motifs and a black calf leather body.
