If you're digging through old photos and wondering why prom dresses 2017 looked the way they did, you definitely aren't alone. It was a weirdly specific year for fashion where the boho-chic aesthetic finally collided with high-glam Hollywood red carpet vibes. Looking back, 2017 was really the peak of a few trends that define that entire mid-2010s era—some of which we still see today, and others that we've happily left in the back of the closet.
The Era of the Two-Piece Set
If you went to prom in 2017, there is a very high chance you or at least five of your friends wore a two-piece dress. This was the absolute "it" look of the season. It usually consisted of a heavily beaded or lace crop top paired with a massive, high-waisted ball gown skirt.
What made this trend so popular was how it broke the traditional "one-piece" rule of formal wear. It felt a little rebellious but still fancy enough for a school dance. Designers like Sherri Hill and Jovani were pumping these out in every color imaginable. Usually, the top was sheer with strategically placed embroidery, and the skirt was either a sleek satin or a giant pile of tulle. It was a look that screamed "I spend a lot of time on Pinterest," and honestly, it photographed incredibly well.
Rose Gold and "Millennial Pink" Everywhere
We can't talk about prom dresses 2017 without mentioning the color palette. This was the year that rose gold officially took over the world. It wasn't just for iPhones anymore; it was the primary color for every sequined gown in the room.
Alongside rose gold, we had the rise of "Millennial Pink." It was that dusty, muted blush tone that felt more sophisticated than the bubblegum pinks of the early 2000s. If you didn't want pink, you probably went for burgundy or navy. Those deep, moody jewel tones were the go-to for anyone who wanted to look "mature." It's funny how every few years we decide that navy blue is the new black, and 2017 was definitely one of those years.
The Rise of Velvet
While satin and chiffon are prom staples, 2017 saw a surprising surge in velvet. It felt a little bit "90s revival," but with a modern twist. Most velvet dresses that year were simple wrap-style gowns or fitted slip dresses in dark colors like forest green or deep wine. They were soft, they were comfortable (mostly), and they looked expensive even if they weren't. The only downside was that wearing heavy velvet in a crowded, sweaty gym or hotel ballroom wasn't always the best practical choice.
Florals and Embroidery
Before 2017, florals were mostly for summer sundresses. But that year, big, bold, embroidered florals became a massive hit for formal wear. We started seeing black or navy dresses covered in vibrant red roses or delicate wildflowers.
It wasn't just a flat print, either. A lot of the prom dresses 2017 featured 3D floral appliqués—flowers that actually popped off the fabric. It gave the dresses a very "secret garden" or "fairytale princess" vibe. It was a nice break from the constant sparkle of sequins and gave a bit of a bohemian edge to the night.
The Pockets Revolution
It sounds silly now, but 2017 was the year we all realized that dresses could—and should—have pockets. Every time a girl found a dress with hidden pockets in the side seams, it was a genuine "stop everything" moment.
"Look! It has pockets!" became the unofficial catchphrase of prom season. It was a game-changer. You could actually carry your lip gloss and your phone without needing to keep track of a tiny, useless clutch all night. Most of the A-line satin dresses that year came with this feature, and it's a trend I think we can all agree should never go away.
Chokers and Statement Accessories
Fashion doesn't stop at the dress, and 2017 had some very specific accessory rules. This was the year of the matching fabric choker. A lot of dresses actually came with a thin strip of matching lace or velvet to wear around your neck. It was a very "Kylie Jenner" influence that trickled down to every prom in the country.
If you weren't doing the choker, you were probably wearing heavy "statement" earrings. Big, sparkly dangles were the way to go, especially if your hair was up in one of those messy-but-perfectly-styled buns that were popular at the time.
High-Low Hemlines and Mermaid Silhouettes
The "high-low" dress—short in the front, long in the back—was still hanging on by a thread in 2017. It was the perfect compromise for people who couldn't decide between a short party dress and a long gown. However, it was starting to get phased out by the dramatic mermaid silhouette.
The mermaid look was everywhere. These dresses were tight all the way down to the knees and then flared out into a dramatic "tail." They were notoriously difficult to dance in, and sitting down was an Olympic sport, but they looked phenomenal in the "pre-prom" photos taken in someone's backyard.
Thrifting the 2017 Look Today
Fast forward to now, and prom dresses 2017 are starting to pop up in vintage shops and on resale apps like Depop or Poshmark. It's wild to think of 2017 as "vintage," but in the world of fast-moving trends, it kind of is.
A lot of people are actually hunting down these older styles because they were made during a time when "boho glam" was at its peak. The quality of the beadwork on some of those mid-2010s dresses is often better than what you find in the cheap "fast fashion" formal wear today. Plus, there's something fun about wearing a dress that has a little bit of history to it—even if that history only goes back a few years.
Why 2017 Still Feels Relevant
I think we look back at 2017 fondly because it was a bit of a turning point. We were moving away from the "neon and bandage dress" era of the early 2010s and moving toward something a bit more refined and romantic. The influence of social media was really starting to peak, so the dresses were designed to look good in photos from every angle.
Whether it was the two-piece sets, the endless rose gold sequins, or the sheer joy of finally having pockets, the fashion of that year had a personality. It wasn't just about looking "fancy"; it was about making a statement. Even the trends that didn't age perfectly (looking at you, matching chokers) still represent a specific moment in time when we were all just trying to look like our favorite Instagram influencers.
So, if you still have your dress from 2017 sitting in a garment bag in your parents' basement, don't be so quick to get rid of it. Trends move in circles, and before you know it, those two-piece floral sets will be the height of fashion all over again. Or, at the very least, you'll have a great piece of nostalgia to look back on when you're laughing at your old prom photos ten years from now.
