When it comes to appropriate colors for a wedding guest dress, there are some "rules" to keep in mind. For example, white is the most obvious no-no unless you're the bride and some people say that red can be considered rude. But a pastel dress for a wedding guest is almost always a good option. Pastel colors include lilac, baby pink, light blue, light yellow and even tones of sage green—basically, anything soft and not too bright. Pastels tend to be romantic, classically feminine and delicate, making them ideal for a special occasion like a wedding.

They also work for almost any dress code, from black-tie gowns to shorter and more casual pieces. And while pastel wedding guest dresses tend to fit best with a spring or summer wedding, they can also work for fall and winter. Pick one of these versatile pastel dresses for wedding guests, and you'll find that you'll almost definitely be able to wear it again.

The Best Pastel Dresses for Wedding Guests

Pastel formal dresses come in every dress style out there, so whether you're attending a very formal wedding or something casual on the beach, you'll probably be able to find something. If you're shopping for a pastel dress for a black-tie wedding, look for a floor-length gown in a solid, soft hue. For a formal or black-tie optional dress code, opt for floor-length or midi styles. Midi dresses are also great for cocktail attire, while something shorter and more laid-back can be a good fit for semi-formal or casual.
