What Is a Tankini?
A tankini is a two-piece swimsuit that combines the coverage of a one-piece with the flexibility of a bikini. It includes a tank-style top and a separate bottom. Many women like tankinis because they offer modest coverage without feeling too restrictive.

One of the best things about a tankini is the ability to mix and match sizes. If you wear a different size on top than bottom, this style makes it easier to get a better fit. It’s also more convenient for bathroom breaks, especially compared to a one-piece swimsuit.
Tankinis come in many styles—halter tops, bandeau tops, racerbacks, and options with built-in bras. You can also find tankinis with tummy control, tankinis for large busts, and high-waisted bottoms for more coverage.
Tankinis are a great choice if you want:
- More coverage than a bikini
- A two-piece option with a modest look
- Better sizing flexibility
- Comfort for chasing kids, swimming, or lounging
What Is a One-Piece Swimsuit?
A one-piece swimsuit is a classic swimwear style that covers the torso in a single piece of fabric. It’s often chosen for its sleek look, full coverage, and support.
- One Shoulder One Piece Swimsuits for Women: The unique one shoulder design and adjustable strap could make it fit well and stay in place, while still very flattering.
- One Piece Bathing Suit for Women Tummy Control: Ruched design fully covers the belly and offers necessary support to show your curves. The removable padded bra of this one piece bathing suit provides enough support and shaping.
- One Shoulder Swimsuits: Full coverage feature could avoid exposure on the beach. The modest bottom could show your good shape and the low back is very cute.
Many women prefer one-piece swimsuits because they stay in place during movement. Whether you’re swimming laps, doing water aerobics, or playing with kids at the pool, a one-piece gives you secure coverage.
One-pieces also come in a wide range of styles. You can find:
- Ruched one-piece swimsuits for tummy control
- Athletic one-piece swimsuits for performance
- High-neck or plunge styles for different coverage levels
- Slimming one-piece bathing suits with mesh panels or built-in shaping
While one-pieces don’t offer the sizing flexibility of tankinis, they often provide better support for the bust and midsection. They’re a top choice for women looking for a streamlined, supportive, and stylish option.
Choose a one-piece if you want:
- A timeless, all-in-one style
- More support during water activities
- A smooth, sculpted look
- Less risk of fabric shifting or riding up

Pros and Cons of One-Piece Swimsuits

One-piece swimsuits are best for women who want dependable coverage, support, and a clean, polished look—especially for swimming, water workouts, or lounging in style.
Which Is Better for Your Body Type?
Choosing between a tankini and a one-piece swimsuit often comes down to body shape. The right style can highlight your strengths and help you feel more confident. Here’s how to pick the best option for your body type:
Pear-Shaped (Wider hips, smaller top)
- Best choice: Tankini with a bold or detailed top and darker bottoms.
- Why: It balances your shape and draws attention upward.
- Tip: Look for ruffles, prints, or padded tops.
Apple-Shaped (Fuller midsection)
- Best choice: One-piece with ruching or tummy control panels.
- Why: These styles smooth the midsection and create definition.
- Tip: A V-neckline adds length and draws the eye upward.
Athletic or Straight (Little waist definition)
- Best choice: Either works—look for styles that create curves.
- Why: Details like side cutouts, color blocking, or high-cut legs enhance your shape.
- Tip: Tankinis with a peplum top add volume at the hips.
Hourglass (Balanced top and bottom, defined waist)
- Best choice: Both tankinis and one-pieces work well.
- Why: You can highlight your curves with fitted styles that offer support.
- Tip: Choose designs that cinch the waist and support the bust.
Everyone’s body is unique. The goal is to find a swimsuit that fits comfortably, flatters your shape, and makes you feel good—whether it’s a tankini or a one-piece.
When to Choose a Tankini
A tankini is the perfect middle ground between a bikini and a one-piece. But when is it the better choice? Here are a few times when a tankini really shines.
1. You Need Separate Sizes for Top and Bottom
Tankinis let you mix and match. If you’re larger on top or bottom, you can buy the sizes that actually fit—no more squeezing into a one-piece that’s too tight in one area.
2. You Want Easier Bathroom Breaks
One-piece suits can be a pain when wet. Tankinis make it simple—just pull down the bottom, no full undressing required.
3. You Prefer More Coverage than a Bikini
Tankinis offer modesty while still feeling fun and flexible. Many styles cover the midsection, and high-waisted bottoms add even more coverage.
4. You Like to Mix Styles and Colors
Want a printed top and solid bottom? Or different tops for different days? Tankinis give you style variety without buying multiple full suits.
5. You’re Active but Not Doing Lap Swims
Tankinis work great for beach walks, lounging, chasing kids, or casual swims. They may ride up in rough water, but they’re fine for everyday use.
When to Choose a One-Piece
One-piece swimsuits offer full coverage, support, and a classic style. But when is a one-piece the better option? Here are some situations where a one-piece makes more sense than a tankini.
1. You Need More Support
Many one-piece swimsuits include built-in bras, tummy control, and shaping panels. If you want lift, structure, or smoothing, a one-piece often delivers better results.
2. You’re Swimming Laps or Doing Water Workouts
One-piece suits stay in place. Whether you’re diving, doing laps, or in a water aerobics class, they won’t ride up or shift like a tankini might.
3. You Want a Slimming, Sculpted Look
Ruched designs and dark colors can help create a flattering shape. One-pieces hug your body in a way that smooths curves and supports your core.
4. You Prefer a Simple, One-and-Done Style
A one-piece is easy—just put it on and go. No need to coordinate pieces or worry about adjusting your top or bottom.
5. You Have a Shorter Torso or Petite Frame
One-pieces can help elongate the body visually. Look for V-necks or high-cut legs to create the illusion of length.
Final Thoughts: Which Swimsuit Style Is Best for You?
When it comes to tankinis vs one-piece swimsuits, there’s no one-size-fits-all answer. The best swimsuit is the one that fits your body, supports your needs, and makes you feel confident.
Choose a tankini if:
- You want sizing flexibility for top and bottom
- You need easier bathroom access
- You prefer more coverage than a bikini but like two-piece freedom
- You enjoy mixing and matching styles
Choose a one-piece if:
- You need support and coverage for swimming or exercise
- You want a sleek, sculpted look
- You prefer a simple, secure fit
- You’re looking for tummy control or a slimming effect
Your choice depends on your body type, comfort level, and how you’ll use the suit—whether that’s chasing kids at the beach or swimming laps at the gym. Try on both styles, move around in them, and see what makes you feel your best.
FAQs
Are tankinis good for swimming?
Yes, tankinis are good for casual swimming, lounging, and beach days. But for intense swimming or water workouts, a one-piece usually stays in place better.
What swimsuit is best for hiding belly fat?

Do tankinis stay in place while swimming?
Tankinis may shift during active swimming, especially if the top is loose. A snug fit and secure straps help keep the top from riding up in the water.

One-piece swimsuits are a popular choice for older women because they offer more support, coverage, and shaping. However, many tankinis are also designed with mature bodies in mind.
Can I wear a tankini if I have a long torso?
Yes! Tankinis are a great choice for women with long torsos since they don’t pull like some one-piece swimsuits. Look for longer tops for better coverage.
