5 Swimwear Trends That Are Losing Popularity in 2025 — And What to Wear Instead

Swimwear trends are constantly shifting, and what was hot last summer might already feel dated this year. As we step into the summer of 2025, it’s time to clear out the old and make room for styles that feel fresh, chic, and confidently current. While some silhouettes and designs remain forever classics, others have run their course.

Skip the mismatched bikinis and the tie-dye trend.

Mismatched bikinis may have ruled in recent years, but this summer is all about coordinated swimwear. Matching sets — tops, bottoms, and cover-ups — are back in style, with bundled options like Jollkichay’s one-piece with cover-up or Zaful’s 3-piece swimsuits making it easy to pull off the look.

Meanwhile, the tie-dye trend that surged in the early 2020s is fading fast, replaced by more polished and refined styles. Still want prints? Dark paisley is making a comeback for 2025, offering a bold yet sophisticated option.

Super skimpy, string bikinis are falling out of fashion.

Fashion experts Ira Lysa and Dawn Del Russo have observed that super skimpy, string bikinis are losing their appeal for summer 2025. The micro bikini, while bold, offers minimal support and lacks the structure that today’s consumers increasingly expect.

While there’s absolutely nothing wrong with showing some skin — and comfort should always come first — stylists recommend exploring more vintage-inspired shapes and silhouettes for a fresh, flattering update.

Ruffles and graphic prints are out of style too.

Ruffles had their moment in 2024, but this summer calls for sleeker, more minimal swimwear. Instead of frilly styles, go for textured pieces made with ribbed, crinkle, or ruched fabrics — they add interest and flatter the figure without looking outdated.

Playful prints like fruits and bold graphics are also fading out, making way for timeless, understated designs. Still, there’s room for stylish details: embellished straps with pearls, crystals, or rosettes continue to add a touch of luxury to your look.

Give preference to polka dots and sparkles.

Polka dots are making waves this summer, extending beyond dresses and onto swimwear for a playful yet classic vibe. This timeless print is popping up across top swim brands and is set to be a major trend of the season.

For something more eye-catching, sparkly swimwear is taking over the spotlight. From subtle Lurex threads to all-out sequins, high-shine finishes and iridescent fabrics bring glam to the beach. Whether you’re lounging poolside or heading to a beach party, these dazzling styles are all about making a confident statement.

Try cut-outs and tankinis.

Cut-out swimwear is everywhere this summer, offering a stylish twist for one-piece lovers. From simple keyholes to bold midriff slashes, these designs add flair without sacrificing coverage. One-shoulder suits are also trending, giving a modern edge to classic silhouettes.

Another surprise comeback? Tankinis. Once a school pool staple, they’ve been revamped for 2025 with sleek, body-hugging cuts and fun prints. Perfect for those who want more coverage than a bikini but more flexibility than a one-piece — just watch out for creative tan lines.

Opt for a sporty mode.

Not every new suit has to be a two-piece. As fashion consultant and stylist Sara Walker puts it, “Don’t overlook the timeless one-piece — it’s very classic and chic.”

Artist and fashion writer Laura Kirk De Valencia links the growing popularity of one-piece suits to a broader trend: the increasing influence of sportswear on mainstream fashion.

Summer brings a wave of excitement with new trends in everything from shoes and dresses to hairstyles — and yes, it’s officially pedicure season! So, what nail designs should you be eyeing this year? Let’s take a look at the styles ready to make a splash.
