You know what you like. You’re not here for fast fashion, poor fit, or pieces that fall apart after one season. Whether you’re in the water, on the move, or just enjoying some well-earned downtime, the right bikini should feel good, hold up, and look refined.

Here’s how to find a bikini that combines performance, longevity, and classic style—all in one.

1. Fit Your Shape, Not the Trend

Great swimwear starts with great fit. Forget chasing every new cut—look for shapes that feel right on you and offer comfort without constant adjusting.

Some style notes based on body balance:

Hourglass or balanced: Go for styles that follow your natural lines without digging in—secure bands help keep everything in place. We would recommend Cado bikini bottom & Parla bikini top

Athletic or straight: Opt for cuts with curve-enhancing details like high-cut legs or scoop necklines. We would recommend Indi bikini top & Tulu bikini top

Curvier or fuller in certain areas: Choose silhouettes with strategic support through thicker straps, wide bands, or thoughtful fabric structure. We would recommend Floe bikini top & Parla bikini top

Even small details like a clean side seam or angled strap placement can make a difference in how a suit fits and flatters. All our styles have different attributes and well designed constructions.

 

2. Performance Comes First

If you're swimming, moving, or just staying active outdoors, function matters. A well-designed bikini should feel good while you're wearing it—and stay put when you're in motion. Lucky for you all of Tumlas swimwear are made with this in mind, meaning that you are all set from the moment you stumbled into our website.

Look for:

• Secure, comfortable straps that stay in place
• Coverage that doesn’t shift when you’re moving or swimming
• Stitching in strategic places that helps with minimizing movement between fabrics
• High-performance stretch fabric that supports without squeezing
• No underwires needed—smart construction and quality fabric do the heavy lifting. 

 

3. Invest in Quality Materials

You can spot a premium bikini by the way it feels—and how it holds up. Choose suits made with:

• Chlorine- and saltwater-resistant fabric
• Stretch that recovers well, wear after wear
• Fully lined interiors for comfort and opacity
• Textured or technical fabrics that add visual interest and structure

The payoff? A suit that won’t fade, sag, or fall apart after one season. Our swimwear is made with high performance quality fabric from Italy made with the regenerated nylon called ECONYL. This way we can make sure that your swimwear will perform when needed and stay with you for a long time.

 

4. Choose Style That Lasts

Trends fade. Classics don’t. A well-cut bikini in a timeless shade will always feel relevant—and it’s easy to style in different ways, season after season.

Go for:

• Neutral or muted colors: black, brown, green, beige, and so on.
• Minimal design details: clean lines, subtle hardware, tonal stitching
• Simple yet refined cuts that flatter without overcomplicating things
• Pieces that are easy to match with your current wardrobe, for more areas of usage.

Think quiet confidence over loud prints. Picking a style with a timeless design means that you dont have to buy a new piece every season. Good for both your wallet and the environment. Many of our designs are classic and made with this in mind - check out one of our best-sellers Cado bikini bottom. 

5. Smart Shopping Tips

Buying swimwear online doesn’t have to be a gamble. A few key tips can help:

• Know your current measurements (not just your typical size)
• Check the size guide—sizing can vary between brands, Check out our size guide for a complete breakdown 
• Read product descriptions and reviews to get a feel for fit and stretch
• Mix and match sizing Since we always sell each piece individually, keep in mind that you can choose different sizes on tops and bottoms. Usually this is required for a good fit.

Bonus tip: try your bikini on at home in good lighting with a mirror you trust. You'll know immediately if it's a keeper.

Conclusion: Choose Less, Choose Better

Swimwear doesn’t need to be complicated. When you invest in a bikini that fits well, performs beautifully, and looks timeless, you’ll reach for it again and again. Quality over quantity wins—every time.
