What is a Black-Tie Wedding Guest Dress?

Black-tie attire is one of the more strict wedding dress codes (you can learn all about it here). When it comes to dresses, you'll want to stick to darker colors like navy blue and black. Jewel tones can also be acceptable options, especially if you're attending an event in the fall or winter. Of course, like any dress code, there is a bit of flexibility. If you're attending a wedding in the spring or summer, for instance, you might choose to incorporate florals, or other patterns, into your look. Likewise, if the event is taking place at a more casual location, such as a beach or garden, there's an opportunity to experiment more with color. This is where red, green and even orange dresses might come into play. For a black-tie event, we typically recommend sticking to floor-length silhouettes, but midi dresses can work too if they're a bit more elevated in design.
