What’s the Difference Between a Formal and a Semi-Formal Dress?

Formal and semi-formal dresses differ based on event dress codes and styling. Formal attire, often called black-tie, features glamorous floor-length gowns with luxe details like rhinestones, lace, and beading—perfect for galas, weddings, and proms. Popular silhouettes include mermaid, ball gown, and A-line styles.

Semi-formal dresses offer more variety in length and design, making them ideal for homecoming, weddings, and cocktail parties. These styles range from midi to short lengths.

The venue and occasion can also guide your choice—an upscale wedding may call for a floor-length gown, while an outdoor event might be perfect for a sleek midi dress with a stylish neckline.

Are Formal Dresses Always Long?

Not always! While long gowns are classic for formal events, modern formal attire includes various lengths and styles. Windsor’s collection of women’s formalwear features short, midi, and long dresses. Explore dramatic mermaid and column silhouettes for timeless elegance, or opt for trendy alternatives like high-low hemlines and two-piece designs for a fresh take on formal fashion.

Find your perfect formal dress at Windsor any time of year, available online, in-app, and in over 350 stores across the U.S. and Canada. Shop now for trend-driven styles that make you shine and every event unforgettable!
