Common Types of Swimsuits

Swimwear comes in a variety of styles, each designed to suit different body types, preferences, and activities. From the classic one-piece to the daring bikini, understanding the range of swimsuit types is essential for making an informed choice.

One-Piece Swimsuits

The one-piece swimsuit is a timeless classic, offering a clean, streamlined look that never goes out of style. It’s often chosen for its versatility and comfort, providing a solid amount of coverage while still allowing for plenty of movement. Here are some common variations of the one-piece swimsuit:

  • High-Neck One-Piece: Known for its elegant and sporty design, this style features a higher neckline and provides additional coverage around the chest. It’s ideal for those who want a bit more support and a modest yet flattering look.
  • Plunging Neckline One-Piece: A bold choice, the plunging neckline offers a deep cut in the front or back, creating a daring yet sophisticated style. It’s perfect for those who want to show a little more skin while maintaining the full coverage of a one-piece.
  • Athletic Cut One-Piece: Designed for active swimmers or anyone participating in water sports, the athletic cut one-piece offers a snug fit with a focus on mobility and support. It typically has thicker straps and a simple design, making it a favorite for comfort and performance in the water.
These are three common one-piece swimsuits: a high neck one-piece, a deep V-neck one-piece, and a sporty cut one-piece.

Bikinis

The bikini is arguably the most popular swimsuit style, known for its versatility and variety. Perfect for those who prefer a more revealing look or want to mix and match styles, bikinis come in countless designs and cuts. Here are some of the most common types:

  • Triangle Bikini: This iconic style features two triangular cups that cover the bust, with ties at the neck and back. The simplicity and adjustable nature make it a favorite for those seeking a customizable fit.
  • Bandeau Bikini: A strapless design, the bandeau bikini features a rectangular band that covers the bust. This style is ideal for those who want to avoid tan lines and prefer a minimalist look.
  • High-Waisted Bikini: A modern twist on the classic bikini, the high-waisted bottom offers more coverage around the hips and stomach, creating a retro vibe. It’s perfect for those who want to balance style with comfort, providing a flattering silhouette while still showing off some skin.
  • Thong and Cheeky Bikinis: For those who prefer minimal coverage, thong and cheeky bikinis are designed to highlight the derriere. They offer a bold, daring style that’s perfect for lounging by the beach or poolside.
These are three common bikini swimsuits: the triangle bikini, the deep-cut bikini, and the high-waisted bikini.

Rash Guards

Rash guards are functional swimwear pieces originally designed for surfers but have become popular among swimmers, water sport enthusiasts, and anyone seeking sun protection. They typically come in the form of a fitted, lightweight shirt made from quick-drying, stretchable materials like spandex or polyester.

  • Short-Sleeve and Long-Sleeve Options: Depending on the level of sun protection or activity, rash guards are available in both short- and long-sleeve styles. Long sleeves are especially beneficial for UV protection and avoiding abrasions during water sports.
  • UPF Protection: Many rash guards are made with built-in UPF (Ultraviolet Protection Factor), providing a shield against harmful sun rays and reducing the need for sunscreen on covered areas.
  • Pairing with Swim Bottoms: Rash guards are usually worn over bikini bottoms, swim shorts, or board shorts. This makes them suitable for active days at the beach, snorkeling, paddleboarding, or other water-based activities.

Swim Dresses

Swim dresses offer a graceful alternative to traditional swimwear, combining the functionality of a one-piece with the look of a casual dress. These swimsuits feature an attached skirt that extends over the hips or thighs, providing additional coverage and a flattering silhouette.

  • Flattering Fit for All Ages: Swim dresses are especially popular among women seeking modesty or a more feminine, vintage-inspired look. They help enhance confidence by softly covering areas like the stomach and upper thighs.
  • Built-in Bottoms: Most swim dresses come with integrated bikini briefs or shorts underneath the skirt, ensuring both style and practicality for swimming or walking on the beach.
  • Variety in Design: From sporty racerback styles to elegant halter tops and ruffled hems, swim dresses are available in a wide range of cuts and colors to suit every personality and preference.

Swimwear Fits: Finding Your Ideal Shape

Choosing the right swimsuit fit is just as important as selecting the style. A well-fitting swimsuit enhances comfort, flatters your figure, and boosts confidence—whether you’re swimming laps or lounging in the sun. This section explores the key aspects of finding the ideal swimwear fit based on body shape, support needs, and personal preferences.

Understanding Body Shapes

Different body shapes benefit from different swimsuit fits. While everyone’s body is unique, these general guidelines can help in identifying flattering options:

  • Hourglass: Balanced bust and hips with a defined waist. Look for structured bikinis, high-waisted bottoms, or belted one-pieces that highlight the waistline.
  • Pear-Shaped: Narrower upper body with wider hips. Choose swimsuits with embellished tops to draw attention upward, and darker, simpler bottoms to streamline the hips.
  • Apple-Shaped: Fuller midsection and bust with slimmer hips. Opt for tankinis or ruched one-pieces that offer tummy control and support around the bust.
  • Athletic/Rectangle: Straight silhouette with fewer curves. Create dimension with ruffles, cutouts, or padded tops to accentuate the bust and hips.

Fit Considerations

  • Bust Support: For larger busts, choose suits with underwire, molded cups, or thick straps for added lift and comfort. For smaller busts, triangle or bandeau tops with padding can enhance curves.
  • Tummy Control: Look for swimsuits with ruching, high-waisted bottoms, or control panels to smooth and shape the midsection.
  • Adjustable Features: Swimsuits with adjustable straps, ties, and back closures provide a more personalized and secure fit.
  • Leg Openings and Coverage: Higher leg cuts elongate the legs, while boyshort or skirted bottoms offer more coverage and comfort.

Fabric and Material Choices

The performance, comfort, and appearance of swimwear are heavily influenced by the materials used. Swimwear fabrics need to be flexible, durable, and resistant to sun, salt, and chlorine. Choosing the right material is essential for achieving the desired fit and function.

Common Swimwear Fabrics

  • Nylon (Polyamide): Lightweight and smooth, nylon is known for its excellent stretch and quick-drying properties. It’s commonly blended with spandex to provide a snug, comfortable fit.
  • Spandex (Elastane/Lycra): Often blended with other fibers, spandex gives swimwear its signature stretch and shape retention. It’s essential for creating form-fitting and flexible designs.
  • Polyester: More resistant to chlorine and UV exposure than nylon, polyester is a popular choice for athletic and long-lasting swimwear. It’s durable, colorfast, and often used in competitive swimwear.
  • PBT (Polybutylene Terephthalate): A type of textured polyester, PBT offers excellent stretch and recovery. It resists fading and maintains elasticity even after repeated use in chlorinated water.

Specialty Fabrics and Features

  • Ribbed and Textured Fabrics: These add visual interest and enhance body contouring while providing the same stretch and support as smooth materials.
  • Eco-Friendly Options: Recycled materials such as ECONYL® (regenerated nylon) and REPREVE® (recycled polyester) are gaining popularity for sustainable swimwear collections.
  • Lined and Double-Layered Fabrics: Many swimsuits are lined for added opacity, support, and comfort.

Swimwear Trends

Swimwear fashion continues to evolve, and 2025 has brought fresh takes on classic silhouettes, with an emphasis on flattering fits, bold design elements, and functional beauty. Here’s a look at the swimwear styles currently trending:

  • Cut-Out One-Pieces: One-piece swimsuits with strategic cut-outs at the waist, back, or chest are a favorite this season, balancing coverage with a modern, edgy vibe.
  • Textured Fabrics: Ribbed, crinkled, or smocked textures are trending, adding depth and interest to simple silhouettes.
  • Asymmetrical Necklines: One-shoulder swimsuits and tops bring a fashion-forward edge, ideal for both swim and poolside lounging.
  • Sporty Swimwear: Activewear-style swimsuits with zip fronts, racerbacks, or long sleeves are growing in popularity, appealing to those who blend style with performance.
