It was 2006. We were all obsessed with flavored lip gloss, Claire’s accessories, and the vague hope that we might find a mermaid in a beach club pool. If you grew up in that era, you know exactly which dress I'm talking about. The Aquamarine movie dress wasn't just a costume; it was a cultural reset for every girl who wanted to look like she’d just stepped out of the ocean and into a high school dance.
Honestly, looking back at the film now, it’s a total time capsule. Sara Paxton played the title role with this weird, endearing charm, but it was her transformation for the "Last Splash" party that really stuck. That dress—the shimmering, iridescent, teal-blue mini—became the blueprint. It was meant to look like scales without being literal. It was high-shine, slightly holographic, and perfectly captured that "mermaid-core" aesthetic long before TikTok gave it a name.
Costume designer David C. Robinson had a weirdly specific task. He had to make a girl who was literally a fish five minutes ago look like the coolest person in a coastal town. And he nailed it.
The Design Secret Behind the Aquamarine Movie Dress
The dress isn't just blue. That’s the first thing people get wrong. If you look closely at the high-definition stills from the movie, the fabric is a complex layering of aquamarine, seafoam green, and silver threads. It’s a sequined masterpiece that catches the light in a way that mimics the sun hitting the surface of the water.
Most movie costumes are built for durability, but this one needed to move. It had to be fluid. Robinson chose a silhouette that was very "of its time"—the babydoll cut. It had those thin spaghetti straps and a slightly flared skirt that allowed for movement during the dance scenes with Raymond (played by Jake McDorman, the heartthrob of the week).
People often ask if the dress was a specific brand. While many pieces in the film were sourced from mid-2000s staples like Roxy or Billabong to keep the "beach town" vibe authentic, the Aquamarine movie dress was a custom creation. It had to be. You can't just find that specific level of mermaid-sheen on a rack at the mall, even in 2006. The bodice was structured to give that sea-shell-inspired look, while the sequins were applied in a way that felt organic rather than geometric.
Why We Are Still Obsessed With It in 2026
Fashion is cyclical. Everyone knows that. But the obsession with the "mermaid aesthetic" has reached a fever pitch lately. Between the live-action Little Mermaid and the rise of "siren-core" on social media, designers are constantly looking back at the mid-2000s for inspiration. The Aquamarine movie dress represents a specific kind of nostalgia. It’s not the dark, edgy Y2K look; it’s the "sun-drenched, optimistic, glittery" side of the era.

I saw a creator recently try to recreate the dress using modern fabrics, and they pointed out something interesting. The original dress used a type of "mermaid scale" sequin that actually reflects colors differently depending on the angle. This is called "structural coloration" in nature, and the costume designers mimicked it perfectly.
The Evolution of the Last Splash Look
The party scene was the climax of the movie. Everything led to that moment. Hailey and Claire (JoJo and Emma Roberts) were trying to prove that love exists, and Aquamarine was the walking proof.
The dress worked because it didn't look like a costume. It looked like something a teenager would actually wear to a party, albeit a very fancy one. It bridged the gap between fantasy and reality. When you see Aquamarine walking down the stairs, she’s wearing these platform sandals and has those iconic blue-streaked hair extensions. It was the peak of "maximalist" styling.
- The blue hair streaks were actually a plot point (her hair turned blue in the moonlight).
- The dress featured a lace-up back, common in mid-2000s formal wear.
- The sequins were hand-sewn to ensure they didn't catch on the fabric.
Finding the Dress Today: A Hunt for the Holy Grail
If you’re looking to buy the actual Aquamarine movie dress, I have some bad news. Movie props are usually archived or sold at private auctions. A few years ago, some of the original costumes from the film surfaced on specialized movie memorabilia sites, but they are incredibly rare.
However, the "dupe" culture is real. Because the film has such a cult following, several boutique brands have released "inspired" versions. You’ll find them under labels like "Mermaid Sequin Mini" or "Iridescent Party Dress."
But honestly? Most modern versions miss the point. They’re too shiny or too green. The original had a specific softness to the blue—like a shallow Caribbean lagoon. If you’re trying to DIY this, look for "iridescent lurex" or "holographic mesh." Those are the fabrics that will get you closest to that 2006 magic.

The Cultural Impact on Gen Z and Beyond
It’s funny how a movie that was largely dismissed by critics at the time has become a visual touchstone for an entire generation. Aquamarine wasn't trying to be high art. It was a movie about female friendship, which is why it sticks. The dress is a symbol of that friendship—Hailey and Claire putting their own styles aside to help their friend look her best.
We see the influence of the Aquamarine movie dress in modern red carpets. Look at Taylor Swift’s Eras Tour outfits or Dua Lipa’s mermaid-inspired gowns. There’s a direct line from that teal sequined mini-dress to the high-fashion mermaid looks we see today. It taught us that you can be "extra" and still be cool.
How to Style a Modern Version
If you're brave enough to rock the look today, don't go full 2006. Skip the chunky platform flip-flops. Instead, pair a sequined teal dress with minimalist silver heels. Keep the hair sleek—maybe a "wet look" style to lean into the mermaid theme without looking like you're going to a costume party.
The key to making the Aquamarine movie dress work in 2026 is balance. The dress is the star. Everything else should be supporting cast.
The Realism of the "Scale" Fabric
One detail that often gets overlooked is how the dress reacted to water. Remember, she’s a mermaid. There are scenes where the dress gets damp, and the costume team had to ensure the sequins wouldn't lose their luster or fall off.
They used a synthetic backing that wouldn't stretch or sag when wet. This is a technical nightmare for costume designers. Most sequins are glued, but for a "water-heavy" movie like Aquamarine, they had to be reinforced. It’s these tiny, invisible details that make the dress look "real" on screen.

The dress also had to compete with the actual mermaid tail, which was a $250,000 piece of animatronic engineering. The fact that we remember the dress just as vividly as the tail says everything about the power of the design.
Actionable Steps for Recreating the Vibe
If you are obsessed with the Aquamarine movie dress and want to incorporate that energy into your wardrobe or an upcoming event, here is how you actually do it without looking like a throwback meme.
First, source the right color. You aren't looking for "Royal Blue." You are looking for "Cyan" or "Tiffany Blue" with a silver undertone. Look for fabrics described as "two-tone" or "chameleon." These change color as you move, which is the hallmark of the original costume.
Second, focus on the fit. The babydoll silhouette is back in style, but it can easily look like a nightgown. Ensure the bodice is fitted and the straps are delicate. If the straps are too thick, you lose that "ethereal" look.
Third, the accessories. In the movie, Aquamarine wore those giant starfish earrings (which she literally talked to). Maybe don't do that. Instead, look for raw pearl jewelry or sea-glass necklaces. It keeps the nautical theme but brings it into a more sophisticated, modern territory.
Finally, understand the lighting. Sequins like the ones on the Aquamarine movie dress look best in low, warm light or direct sunlight. If you're wearing this to a nighttime event, make sure the fabric has enough silver in it to reflect the ambient light, otherwise, you'll just look like a dark blue blur in photos.
The legacy of this dress isn't about the fabric or the price tag. It's about the feeling of that specific summer—the one where anything felt possible, and your best friends were the only people who mattered. That’s why we’re still talking about it twenty years later. It’s a piece of nostalgia you can wear.
Invest in quality sequins if you're buying a tribute piece. Cheap ones will scratch your arms and lose their color after one wash. If you want that Aquamarine glow, you have to go for the high-density sequins that are layered like actual fish scales. That’s the secret to the shimmer.
