Got an invite but have nothing that’ll make the formal cut? We’ve been there. Make that grand entrance in dresses that do the work for you—tiered skirts, sweetheart necklines, next-level details, and plush fabrics; these babies are designed to make you look serious goals, with no effort required. And btw, it’s always smart to have something fancy on standby, invite or not. (hint: stock up now.) Just don’t forget to burn.up.that.dancefloor.
