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. Unique details like faux pearl beading, rhinestone embellishments, and satin trims elevate each dress, making them perfect for fall or winter weddings where elegance is key.

Picture yourself gliding across a candlelit venue in a floor-length gown with an alluring high front slit, or standing out in a rhinestone-embellished dress with delicate adjustable ties.

These luxurious touches make Windsor’s long wedding guest dresses the perfect choice for formal or black-tie weddings. 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.
