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.

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.
