Designers are showing skin for spring 2024 by way of necklines that drop off one shoulder or two. For a sultry evening look, draw inspiration from Alejandra Alonso Rojas's slip dresses, with high necklines that pull to one side or another. Altuzarra brought back the cold shoulder from the early aughts with off-the-shoulder silhouettes that are held up by spaghetti straps at the neckline. And Rosie Assoulin opted for a classic one-shoulder silhouette with cropped tops that featured a short sleeve on one side and nothing at all on the other.
