Stunning Long Wedding Guest Dresses For Fall & Winter Events

Make an unforgettable entrance with Windsor’s long wedding guest dresses, designed for those who want to captivate from the moment they arrive. From flowing maxi dresses to form-fitting mermaid and trumpet styles, our long guest dresses offer silhouettes that flatter every body type.

Whether you prefer a timeless satin gown or an asymmetrical design with a contemporary twist, our collection has something for every style. Find your perfect fit and step into the season with confidence.
