As summer approaches with its sunny days, the perennial dilemma returns: Which swimsuit to choose for 2021? What cuts, patterns, and colors are in vogue? Each season introduces fresh shapes, materials, and trends essential for refreshing your beach wardrobe, showcasing new favorites, and accentuating your curves. Stay ahead with the latest swimwear must-haves.

This season, swimwear shines with vibrant colors, graphic patterns, gathers, and asymmetrical cuts. The one-piece definitively eclipses the classic bikini. Here's a close-up on the standout pieces, cuts, and patterns for summer 2021.

The One-Piece Swimsuit: Summer 2021's Top Trend

Following 2020's strong revival, the one-piece swimsuit solidifies its status as the essential beachwear piece for 2021. This timeless classic is endlessly reimagined with asymmetrical details, cutouts, and structured supports to sculpt the silhouette and flatter every body type.

The Cut-Out Swimsuit

The 2021 trend leans into cut-outs, delivering a sexy yet elegant update to the traditional one-piece. With refined belly openings, it subtly reveals tanned skin while enhancing your curves—a staple for discerning fashion lovers.

The Asymmetrical Swimsuit

Having conquered dresses and tank tops, asymmetrical cuts now transform swimwear. The one-shoulder style flatters all figures, positioning you as the beach style leader this summer.

The Cut-Out Swimsuit

Echoing the sexy allure of cut-outs, 2021's openwork designs captivate with lateral, ventral, circular cuts, or slender fabric strips. They discreetly highlight curves for a modern, sensual beach vibe.

Underwired Swimsuit

Available in one-piece or bikini styles, the underwired swimsuit excels at celebrating the female form. It subtly lifts cleavage, creates a push-up effect for smaller busts, or supports fuller ones—versatile perfection for every silhouette.

The Laced Swimsuit

Whether on the back, neckline, sides, abdomen, or bikini top, lacing surges in popularity this season. In one-pieces or bikinis, it playfully accentuates curves, crowning you beach royalty.

2021 Swimwear Prints: Vintage Vibes Take Center Stage

Embracing vintage in ready-to-wear and swimwear alike, 2021 prints feature floral motifs, retro details, and classic gingham checks.

Gingham Check Swimsuit

Spring-summer 2021 kicks off with timeless gingham checks. On underwired, cut-out, asymmetrical, or ruffled designs, it adapts seamlessly as a beach essential.

Retro Print Swimsuit

Under a vintage banner, 2021 offers bold prints: floral, wax, ethnic, geometric, Aztec, or exotic. Indulge your tastes—the challenge is picking just one.

2021 Swimwear Materials: Textures That Elevate Your Look

Beyond cuts, colors, and prints, materials define 2021's trendsetters. Here's what to prioritize.

The Gathered Swimsuit

Popular on dresses and necklines, gathered fabrics now grace swimwear with undeniable charm. Sensual and curve-enhancing, especially in bandeau styles, it's a season standout.

Crochet Swimsuit

Luxury houses pioneered crochet's comeback in spring-summer 2021 collections—from bags to dresses. Once outdated, crochet now claims prime swimwear real estate with fresh, modern appeal.
