One-piece swimsuits used to have a reputation: practical, safe, modest—maybe even boring. But that’s no longer the case. Today’s one-pieces are just as bold, flattering, and fun as any bikini. They offer support where it matters, coverage without compromise, and a sleek silhouette that feels timeless.
Whether you’re poolside, lakeside, or chasing toddlers at the splash pad, one-piece swimsuits can meet your lifestyle and your style preferences.
Here are 10 one-piece swimsuits you’ll actually want to wear all summer, each designed to support real bodies and make you feel confident doing whatever summer throws your way.
1. The High-Neck Mesh Inset One-Piece
For anyone who wants coverage with a little edge, this style is a win. The high neckline keeps you supported and sun-protected, while mesh insets add just enough visual interest without being over the top.
Perfect for:
- Paddleboarding
- Beach volleyball
- Minimalist style lovers
It gives a sporty vibe while still feeling chic, and it works for a wide range of bust sizes.
2. The Belted Retro One-Piece
A belted swimsuit instantly creates shape and structure, giving the illusion of a defined waistline. Look for options with contrast piping or vintage-inspired colors for a glam 1950s nod.
Perfect for:
- Lounging with a book
- Resort vacations
- Pairing with linen pants post-swim
These are also great for turning heads without showing a ton of skin. Elegant and flattering.
3. The Wrap Front One-Piece
Wrap-style swimsuits do what wrap dresses do: flatter your curves and define your waist. They also offer adjustable fit and subtle shaping around the midsection.
Perfect for:
- All-day comfort
- Postpartum wear
- Pool-to-brunch outfits
Swimsuits For All carries beautiful One-Piece Swimsuit options that are perfect for frequent swimmers or those who want extra durability.
4. The Low-Back Sleek One-Piece
If you want something that feels minimal but striking, go for a suit with a plunging back. It offers an unexpected detail while keeping things classic from the front.
Perfect for:
- Sunset swims
- Elegant resort vibes
- Understated glam
Choose solid colors for a clean look or metallics for something more modern.
5. The Square-Neck Compression One-Piece
This swimsuit is all about structure and support. The square neckline frames your collarbone beautifully, and built-in compression makes it feel secure without feeling restrictive.
Perfect for:
- Lap swimmers
- Moms on the go
- Clean, minimalist styling
Compression suits are ideal for those who want to feel “held in” without sacrificing movement or comfort.
6. The Ruffle Shoulder One-Piece
Add some softness to your summer look with a swimsuit that features shoulder ruffles or flutter sleeves. This style draws attention upward and gives a slightly romantic feel.
Perfect for:
- Pool parties
- Photoshoots
- Date days at the lake
It’s a flirty silhouette that still offers coverage, and it works well for pear-shaped bodies.
7. The Zip-Front Surf One-Piece
This is your go-to for action-packed days. A front zip makes it easy to get on and off, and the sleek design usually includes long sleeves or higher necklines for sun protection.
Perfect for:
- Surfing or paddleboarding
- Long days in the sun
- Sporty looks with sneakers or sandals
Swimsuits for All offers several versions of this with functional UV protection, too.
8. The One-Shoulder Statement Swimsuit
For those who want to turn heads while staying comfortable, a one-shoulder suit delivers. It’s asymmetrical, elegant, and works surprisingly well for swimming.
Perfect for:
- Resort lounging
- Girls’ weekend trips
- Tucking into a skirt for beachside dinners
Pro tip: Choose one in a rich jewel tone or modern print for maximum impact.
9. The Shirred Side Control One-Piece
Shirring is your secret weapon if you want a bit of midsection camouflage without feeling like you’re hiding. It flatters without flattening.
Perfect for:
- Confidence boosters
- Family beach days
- Transitioning from one-piece skeptic to one-piece devotee
Swimsuits for All’s one-pieces with tummy control are known for their comfort and fit without the sausage-casing effect.
10. The Convertible Strap One-Piece
Versatility is key in a good capsule wardrobe, and convertible straps let you switch between styles: halter, criss-cross, traditional—whatever suits your plans for the day.
Perfect for:
- Changing tan lines
- Mixing with different coverups
- A custom-feeling fit
If you only want to pack one suit for a weeklong trip, make it this one.
How to Make One-Pieces Work Harder
One-piece swimsuits are no longer just beachwear. You can style them as:
- Bodysuits with high-waisted jeans or flowy skirts
- Layering pieces under linen button-ups
- Base layers for athletic activities like kayaking or hiking
They’re also perfect for moms who want to bend, lift, and chase without fussing with their outfit.
What to Look For When Buying
- Bust support: Underwire, molded cups, or thick straps for lift and hold
- Tummy smoothing: Shirring, panels, or strategic seams
- Fabric: Look for stretch, chlorine resistance, and lining
- Straps: Adjustable or convertible for comfort and versatility
- Colors: Solids are sleek, prints are playful, color blocking adds shape
Final Thoughts
A one-piece swimsuit can be functional, flattering, and fun. Whether you’re headed on vacation, staying poolside with your kids, or just want something you can feel good wearing all day, the right one-piece delivers.
Brands like Swimsuits for All make it easy by offering a range of styles, cuts, and support levels. If you’ve sworn off one-pieces in the past, it might be time to give them another try—because today’s designs are made to move with you and celebrate your shape, not hide it.
Try one. Or better yet, try three. Your summer just got a whole lot simpler.
