How to Choose a Swimsuit for Swimming vs. Sunbathing

Quick Answer

If you plan to swim laps or play beach sports, choose a swimsuit with a secure fit, chlorine-resistant fabric, and minimal embellishments. For sunbathing and lounging, prioritize style, coverage, and comfort, even if that means delicate fabrics or extra details.

When you shop for a new swimsuit, the first question is usually about style or color. But the most important question is: what will you actually do in it? A swimsuit that works for a morning swim might feel wrong for a day of lounging by the pool, and vice versa.

This guide breaks down the practical differences between swimwear built for activity and swimwear meant for relaxation. You'll learn what to look for in fit, fabric, and features, so you can make a choice that matches your real beach habits.

Fit and Coverage: What Changes Between Swimming and Sunbathing

For swimming, you need a suit that stays in place when you move. Look for a snug fit, secure leg openings, and straps that won't slip. High-waisted bottoms can offer extra security and coverage, but they may create drag in the water. Brazilian-cut bottoms, while stylish, might shift during active swimming. A tanga with a low adjustable hip can be a good compromise if you want less coverage but still need adjustability.

For sunbathing, fit is more about comfort and how you look lying down. You might prefer a high-waisted bottom that flatters your waist or a Brazilian cut that shows more skin. Coverage is a personal choice—there's no wrong answer as long as you feel confident. Just remember that suits with less fabric may not be suitable for swimming if they don't stay put.

• Test the fit by moving around: bend, stretch, and squat to see if anything shifts.
• Adjustable straps and side ties allow you to customize the fit for lounging or swimming.

Fabric and Features: What to Prioritize

Fabric is the biggest technical difference. If you swim regularly, especially in a pool, choose a suit made from chlorine-resistant materials. Some fabrics also offer UPF protection, which is a bonus for outdoor swimming. Textured or shiny fabrics like lamè look glamorous but may not be as durable for frequent swimming. Microfiber is soft and flexible, but check its resistance to chlorine and sun exposure.

For sunbathing, you can afford to prioritize aesthetics. Delicate fabrics, prints, and embellishments are fine because the suit won't face the same wear and tear. However, if you plan to dip in the water occasionally, make sure the fabric won't become see-through when wet and that any decorative elements won't irritate your skin.

• Check the care label for chlorine resistance and UPF rating.
• Avoid heavy embellishments if you'll be swimming—they can snag or weigh the suit down.

Decision Rules: Swim or Sun?

• Primary activity: If you'll spend most of your time swimming laps or playing in the waves, prioritize function over fashion. If you'll mainly lie on a towel or float in shallow water, style can lead your choice. Be honest about how you spend beach days.
• Fabric durability: For regular pool swimming, look for chlorine-resistant fabrics and avoid delicate textures like lamè. For occasional dips, a less durable but prettier fabric is acceptable. Check the fabric content and care label.
• Coverage and security: High-waisted and fuller-coverage bottoms stay put during activity. Brazilian cuts and tangas are better for sunbathing but may shift when you swim. Choose coverage based on your comfort and activity.

Fit Guidance

Best for

• Active swimmers who need a secure, chlorine-resistant suit
• People who prefer more coverage and support while in the water

Not for

• Sunbathers who want minimal tan lines and a glamorous look
• Those who prioritize delicate fabrics and embellishments over durability

The best swimsuit for you depends on how you plan to wear it. If you're a swimmer, invest in a durable, secure suit. If you're a sunbather, choose the style that makes you feel great. And if you're both, consider owning two suits—one for each purpose.
