Styles Made to Flatter

Looking for semi-formal attire for women? Try a classic wrap-front dress or a ruched design for a flattering fit. For something playful yet refined, opt for A-line silhouettes with asymmetrical hems or delicate lace details. Want a sleek, confident look? A fitted bodycon dress with a high slit or an off-the-shoulder neckline brings just the right amount of edge.

From Day Plans to Evening Moments

Each dress is designed to move with your schedule, making it easy to go from daytime events to evening plans. Style with rhinestone jewelry, a chic clutch, and strappy heels for a look that feels complete and elevated. Whether it's a celebration, a brunch, or a special night out, these semi-formal dresses make getting ready feel simple.

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

The difference comes down to how dressy the event is. Formal dresses are usually floor-length gowns made for black-tie events, galas, or upscale weddings, often with dramatic silhouettes and luxe fabrics.

Semi-formal dresses offer more flexibility while still feeling polished. These styles range from chic midi dresses to modern maxi lengths, often featuring details like wrap fronts, ruching, or asymmetrical hems. Perfect for weddings, parties, graduations, and celebrations, a semi-formal dress can easily be styled to fit the moment.

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