What Is the Difference Between a Formal Dress and a Semi-Formal Dress?

The key difference between formal and semi-formal dresses lies in their level of elegance and the occasions they suit. Formal dresses are typically floor-length gowns designed for black-tie events, galas, or upscale weddings, featuring luxurious fabrics and dramatic silhouettes that create a refined look.

Semi-formal dresses offer a balance of sophistication and versatility, making them perfect for cocktail parties, weddings, graduations, and holiday celebrations. These styles range from chic midi-length dresses to stylish maxi options, often featuring trendy details like wrap fronts, ruching, or asymmetrical hems. With the right accessories, a semi-formal dress can still create a stunning, event-ready look.

Not sure which style fits your occasion? Windsor’s team is here to help you find the perfect dress online or in-store.
