This three-quarter sleeve dress can be worn in winter if paired with a long-sleeved turtleneck. It looks light, but it's thick, so you can wear it as is in the early fall. When it gets colder, it goes very well with heat-tech or turtleneck undershirts. It's an easy-to-match, oversized black dress. It can be worn casually or semi-formally. It has a silhouette that makes you look slim.
