There's something so elegant about a dress that shows off your back. Any wedding guest dress is given a sexy upgrade with a backless silhouette. This head-turning style is perfect if you want to make a subtly sexy statement at your next event.

You may typically associate a plunging back with a fancy evening event, however today's selection of wedding guest dresses feature an array of backless silhouettes, whether on an elegant evening gown or a sweet daytime cocktail dress—and they don't have to be reserved for summer weddings, either. Rich fabrications like velvet and jacquard make for perfect winter wedding guest dresses.

While everyone has a different comfort level when it comes to showing skin, the good thing is that there's a backless dress out there for everyone! Whether you want to rock a more modest keyhole back or a daring plunging V-back style, the options are endless.

Things to Consider When Choosing A Backless Wedding Guest Dress

The Dress Code: Keep in mind the formality of the event when choosing your dress. Opt for a gown in an elevated fabric for a more formal evening wedding or go for a mini length for something less formal. While a backless style is appropriate for all levels of formality, the fabric and length of the gown will dictate which styles fit the event.

The Venue: If you're going to be outdoors, keep in mind that your backless dress may be covered up by a jacket if the weather doesn't cooperate. If you know you will be outdoors the whole time, also consider the length of your dress so that it does not drag in the grass the whole time — midi lengths are a great way to ensure you don't worry about your dress dragging all night.

The Season: While backless dresses are typically best for the spring and summer months, there are plenty of great options for fall and winter. Rich fabrics like velvet and long sleeves will ensure you are dressed appropriately for the season while also getting to show off your backless dress. The same can be said for choosing an appropriate color palette for the season. Save your brighter hues dresses for the warmer months and opt for richer tones in the cold months.
