Prom is the night to celebrate everything you have accomplished and everything you're about to take on. Prom is the day to dance the night away with the friends that have seen your highs and your lows, and for that, you'd want to look your best — even if it's during a Zoom call.

Whether you are in the hunt for an affordable prom dress, want to make a power move by opting for a prom suit, or simply want to invest in a dress you'll wear long after your prom memories have been made, there's a site for that. And to help you on your quest, we've rounded up the best websites to buy prom dresses. Just don't forget to buy a comfy pair of shoes to boot – and, yes, we are pleased to inform you that slippers and socks and sandals are also game this year!


Whether you want a chiffon dress, a sequined dress, a long dress, or a short one, Lulus will have the one for you and it will most likely be under $100. Since 2005, Lulus has been carrying affordable frocks that anyone with access to the internet can love. If you opt for Lulus, you won't be disappointed with your pick.


Not only can you always count on Nordstrom for basic and trendy staples, but you can also count on them for gorgeous prom and special occasion dresses. Whether you're looking for short prom dresses, evening gowns, or jumpsuits, you'll find something to suit you at Nordstrom. Plus, Nordstrom offers free shipping and free returns. Win-win.


PrettyLittleThing's prom shop is filled with gems. If you want a statement gown for just one night but that will stay in tip-top shape in case you want to rewear it or resell it afterward, PLT offers more than 300 dress styles for you to choose from. Plus, it also has lots of accessories to match your 'fit so — the perfect one-stop, affordable shop!


If you're all about the latest trends and you want to incorporate them in your prom look, then we suggest you shop at ASOS. The online retailer favored by millions in the world is full of the latest trends you'd been dying to try out since first term. And since they have so many options, we doubt anybody will have the same look. And if they do? It will make for a great IG or TikTok moment. What we love about ASOS's site is that it showcases how dresses look on different bodies, so if you're unsure about the fit, it's easier to grasp what size would be best for you.


H&M's robust selection of party and cocktail dresses has us doing a double-take. From sequined dresses to chiffon maxis, H&M is serving up irresistible prom looks at unbelievable prices. If you're looking for a prom dress that's under $100, you can definitely find it here. (And you can def rewear these long after!)


Don't sleep on Macy's! If its latest TikTok campaign proved anything is that its selection of prom dresses is good enough to go viral on any social media platform. So, if you want a frock that Haley Sharpe, the creator of the "Say So" TikTok dance, would approve of, look no further.

Princess Polly

You've decided you want the perfect slip dress for prom night but don't know where to start your search? The sites above have plenty of options but skimming through all of them might take a toll on your patience. Enter: Princess Polly. Its formal dress shop is full of both long and short slip dresses calling your name for prom night.


Boohoo's prom shop is the most casual out of all these options. Here, you'll find the perfect dress, jumpsuit, or suit that you'll want to rewear long after prom night is over. From cute slip-dresses to sophisticated lace dresses, you'll find a piece that you're guaranteed to have in heavy rotation.


You buy most essentials on Amazon, so why not your prom dress? Especially if time is of the essence, Amazon can be your go-to stop but note that you do run some risks, since most listings are by third-party sellers. But if you do commit to reading the reviews, you can score your dream dress for as little as $20


A lot of the best prom dress websites mentioned above have a great selection of plus size pieces, but if you want to go with a site that's dedicated entirely to plus size dresses, Eloquii should be top on your list. Eloquii's sizing ranges from 14 to 28 and they offer free shipping on orders over $125.


You might associate Shopbop with high-end designers, but this online retailer also carries affordable options. That said, if you do have a bigger budget for your prom dress, we highly suggest you scroll for a few pages. From Free People to Alice + Olivia, you will find your perfect prom dress, jumpsuit, or power suit in no time.


Do you describe your style as vintage or mod-inspired? Then ModCloth will most definitely have a fit for your aesthetic. And, even if you're not a huge fan of vintage pieces, don't cross this shop off your list right away; it also has plenty of trendy options that are 100% unique and exclusive!

Rent the Runway

This year, opt for the more sustainable option when it comes to your prom dress: Renting. Rent the Runway has made one-time rental so easy. If you want to try to switch your consumer ways and start renting clothing, we suggest you check RTR out. RTR offers various plans that can easily fit your needs and budget. The most affordable option, allowing four items per month, starts at $69.


When you think about BHLDN, you might think about wedding and bridesmaid dresses. However, Anthropologie's sister store has over 150+ formal options (including sequined and two-piece dresses) that are more than fit for any occasion — like prom!


Verishop is home to top designers. Its highly curated collections feature top-shelf brands including Bellevue the Label, Dress the Population, Buxom Couture, Marchesa, and more. And, since their shopping experience is easy to filter, you can sort by your exact specification (sleeves, print, length, occasion, etc.) You can even filter your selection by causes, such as sustainability, responsibility, organic, vegan, fair trade, and more.
