I’ve always dreamt of the perfect 21st birthday outfit. As somebody who never refuses a bold night-out look, I was ready to go all out. Unfortunately, my 21st came in the midst of the pandemic, so I couldn't have the glamorous celebration I always anticipated. Of course, I still got dressed up, whatever that meant for pandemic times, but now I always keep an eye out for the outfit that could’ve been.

If you’ve yet to turn 21, though, consider yourself in luck. After years of bookmarking my favorite sparkly minidresses and standout accessories, I’ve gathered a fair understanding of what makes the perfect birthday party outfit. In other words, just consider me your birthday fairy godmother, here to grant you the ultimate 21st birthday ensemble. Whether you plan to have a laid-back celebration or an all-out soirée, I’ve put together looks that capture whatever vibe you may be after.

So without waiting any longer, scroll on for an inside peak at what my imaginary 21st birthday Pinterest board looks like.

If you're looking to take a chill approach to your 21st birthday look, opt for a simple maxi skirt set with edgy cutouts. While this look could easily go glam by styling with heels, instead, pair the set with sneakers to lock down the low-key vibe.

For those unafraid of bold shades, this 21st birthday look is for you. I imagine it is perfect for a day that starts with strolling in the park and ends with a trendy dinner for you and your besties—no outfit change required.

At home, but make it glam. If you plan host a glamorous party at your house or apartment to celebrate, slip into a little black dress and add a statement necklace for a comfortable yet stylish look. Of course, don't forget Insta-worthy drinkware for your guests to cheers you into 21 with.

If your 21st birthday means dancing your heart out under the disco ball, then all you need is a sleek catsuit and a statement necklace for your '70s-inspired look.

If you are picturing elegance for your 21st birthday, channel your inner Blair Waldorf with a bow-accented minidress and a coordinating purse.

If you're a tried-and-true blue-jean baby, ring in 21 by pairing a red satin camisole with your favorite dark wash denim. To make this look going-out worthy, slip on a pair of closed-toe heels before heading out the door.

The formula for a head-turning birthday look, of course, includes a statement corset. Embrace your edgy side with a snakeskin corset, but keeps it flirty with a bubble skirt and slouchy black boots.

If you're celebrating your 21st during the winter months, don't let it hinder your night-out style. Wear that miniskirt hanging in your closet, and pair it with a wool coat that will keep you looking effortlessly cool while staying warm.

You can never go wrong with a casual early aughts–inspired look. If you're having a low-key day with friends, outfit yourself in a Y2K baby tee and racer sunglasses.
