When shopping for a dress to wear to a wedding, there are many things to consider—including the fabric. From fluffy tulle and flowy chiffon to sultry velvet, you have endless options to choose from for the material of your outfit. If you're seeking a sophisticated shine and glamorous appeal, a silk wedding guest dress is your best bet. After all, it doesn't get more lustrous than luxe silk.

Silk is a preferable material for wedding guests for a number of reasons. First, silk has moisture-wicking and temperature-regulating properties, so it's a versatile material for weddings all year round. Silk dresses also come in many different lengths and silhouettes, so there's a style for every aesthetic and wedding dress code. Whether you're after a cocktail slip dress, a casual mini dress or a formal floor-length gown, there's a silky smooth style out there for you.

Officially sold on silk? You're in luck. To help you find the perfect look, we've rounded up the most beautiful silk dresses for weddings in a variety of styles and colors, from soft pastels for summer to deeper jewel tones for autumn.
