The Single Sleeve variety of sleeves literally translates to a dress or piece of attire with only one sleeve where the part of the garment covering the arms is missing on one side. A single sleeve dress is usually characterized by a bare shoulder on one side and an asymmetric neckline which crosses the torso in a diagonal fashion from one shoulder to underneath the opposite arm, creating a single shoulder strap. The origin of the one-shoulder dress is somewhat sketchy as it does not seem to have a very old history; the look can be attributed back to the Ancient Romans and their togas in the early nineteenth century. In modern era of fashion, one-shoulder dressing styles are quite a recent phenomenon to have stormed the fashion scene presently, with their advent occurring around 20th century. The look was popularized in Hollywood by actresses portraying heroines of the past in clinging, one-shouldered costumes; following this, in the 1940s one-shoulder styles began to penetrate the swimsuit and beachwear market. Thanks to designer Roy Halston, who promoted the one-shoulder dress in a huge way, asymmetrical necklines with one sided sleeves started making their way into formal occasions throughout the 60s and the 70s.
Presently, all major fashion houses like Zara, Yves Saint Laurent, etc. have capitalized on the trend to create one shoulder dresses for all occasions and all lengths to standout at any event. Vogue has named the trend as the “chicest way to show some skin this spring”.
