When it comes to dressing for a big event, a dress code that reads 鈥渂lack tie鈥 can easily send you straight into a panic. Because what does that actually mean these days? With colorful sneakers and athleisure essentials popping up on the red carpet and runway, styled alongside glamorous gowns and tuxedos, the line of what is and is not appropriate has become somewhat blurred. But if you鈥檝e been panicking about what to wear to your BFF鈥檚 wedding or that swanky work event, just breathe. We鈥檙e helping you bust through that downright confusing dress code with the easy-to-follow guide below.

WHAT IT IS

If you see that dreaded black tie designation on an invite, be prepared for an elegant evening 鈥 this isn鈥檛 just some backyard shindig. It鈥檚 the type of event where a tuxedo would fit in, so as a rule of thumb, stick with floor-length frocks, formal cocktail dresses or a really dressy suit (sequins, anyone?). If black tie isn鈥檛 indicated for a formal soiree, you can be a bit more lax, but the long silhouette or elevated cocktail dress formula still applies. On the accessories front, statement heels and a fancy clutch would be downright DDG, while glamorous makeup and elegant updos are a must for any upscale event.

LENGTH DOESN鈥橳 MATTER

Floor-length gowns definitely have a formal feel, but they aren鈥檛 the be-all-end-all of black-tie dressing. Midi and short dresses are fair game too, so why limit yourself? If you鈥檙e stepping out of the proverbial floor-length box, just keep the following in mind: Short or cocktail dresses shouldn鈥檛 be more than an inch or two above the knee, opt for classic silhouettes (think: A-line) and look for details like embellishments or metallic fabrics that lend a more glamorous aesthetic to your overall look.

LOOK BEYOND BLACK

Just because there鈥檚 black in the name doesn鈥檛 mean you鈥檙e stuck sporting the classic hue (although it is an easy, foolproof option) for a black-tie event.
