21st Birthday Dresses

Twenty. One. It’s a milestone birthday—so make this year’s celebration a big one! Ring in the next year with the most stylish 21st birthday dresses for the most fabulous b-day party. Whether you’re throwing a super-glam soiree or going for a more laid-back get-together, we’ve got the perfect pieces to make this birthday the best one yet!

A Fashion-Packed Birthday
It’s the big 21 and you certainly have a big reason to celebrate. Heading out with the girls? Fun and flirty picks are perfect for dancing the night away. Go for a fitted bodycon dress featuring the hottest trends of the season. We’re talking about cold-shoulder cutouts, ruffle accents, illusion panels or eye-catching necklines. And you can’t go wrong with something sparkly! Sequin embellishments or metallic details will sure help you stand out and shine. For those who aren’t afraid of pattern, allover floral print, colorblocking or bold stripes are fitting for the fashionable birthday girl. Complete your 21st birthday look with stunning accessories, statement shoes and a chic clutch!

Celebrate in Style
The festivities call for something easygoing? Commemorate your 21st birthday any way you like with pretty dresses perfect for the occasion. Go for stunning options with a more casual vibe like a long-sleeve maxi dress or a fit-and-flare silhouette with bell sleeves. Heading to dinner with your besties? A lace sheath or shift dress is equal parts classic and chic. Put together a cute outfit with flats or sandals (depending on the weather and time of year) plus a crossbody bag or clutch for taking along your birthday essentials.

A big year like your 21st deserves a special look. Make sure to check out the stunning selection of 21st birthday dresses at Macy’s. No matter how you’re celebrating, we’ve got just the right pieces to create a fun and fab birthday look!
