9 Sorority Formal Dresses for the IT Girl of the Chapter

If prom or homecoming said “absolutely not” to the dress you really wanted to wear, sorority formals are your redemption arc. It’s your moment to finally wear the dress you’ve been manifesting since you made that Pinterest board in high school (and look so iconic that your chapter will still be talking about it long after you’ve graduated).

To make sure you serve, we’ve rounded up sorority formal dresses that’ll have you looking like a 10, right alongside your equally fabulous sisters.

What Is a Sorority Formal?

A sorority formal is one of the most fabulous events in Greek life — basically your chapter’s version of prom, but better. It’s your chance to get all dolled up and make core memories with your sisters (and maybe a cute plus-one). Think Homecoming, but without the curfews, with way better outfits, and so much more glam.

What Do You Wear to a Sorority Formal?

The short answer? It depends on the theme, which is why your first move should always be to clarify that.

Generally speaking, sorority formals follow a similar dress code to homecoming, but with way more freedom. You can’t go wrong with black-tie sorority outfits, so consider floor-length gowns, chic cocktail dresses, or even elegant jumpsuits and two-piece sets. Just make sure your formal sorority dress matches the overall vibe of the night (and maybe double-check the invite one more time, just to be safe).
