The most inspiring party and birthday dresses spark confidence and elegance, making you (and the night) unforgettable. But parties mean different things to each of us, so what exactly is meant by party attire?

Formal event: Upscale gowns tend to focus on one core feature. We're talking puff sleeves, luxurious fabrics (satin, anyone?) and dramatic silhouettes.

Cocktail party: Bring back the LBD or drape yourself in the perfect cocktail dress starring bold colors, sequin detailing or a statement long sleeve.

Casual occasion: Who says you can't shine on a Tuesday evening? With the right accessories and a pair of kitten heels, you can dress up even the simplest casual dress.

Birthday party: Celebrate your special day with the perfect birthday dress. Whether you want to go a little extra, with sequins, lace, satin or silk, or keep it minimalist with neutral tones and simple silhouettes, these birthday dresses will make sure your look is on point for a day (or night) to remember.

Regardless of your event, the life of the party starts with the perfect dress. And endless party dress selections just got way more accessible.
