Expert Tips: How to Choose the Right Tankini for Your Body 


Determine Your Body Shape

Pear Shape: Opt for darker bottoms and patterned or embellished tops to draw attention upward.

Hourglass: Highlight your curves with fitted tankinis that cinch at the waist.

Apple Shape: Look for tankinis with empire waistlines and supportive tops to define your midsection.

Rectangle: Create curves with ruffled tops or details and choose bottoms that add volume.

 

Consider Your Skin Tone

Choose colors that complement your skin tone for a more vibrant look.

Bright colors and bold patterns suit warmer skin tones.

Cool-toned skin can be flattered by jewel tones and pastel shades.

 

Think About Support and Comfort

If you need extra support, choose tankinis with built-in bras, underwire, or adjustable straps.

For active days, look for styles with secure fits and thicker straps.

 

Pick Flattering Styles and Details

Ruffles, ruching, and draping can enhance or conceal certain areas.

High-waisted bottoms provide tummy coverage.

Halter or bandeau tops can provide different levels of support and coverage.


Focus on Fabric and Fit

Choose quick-drying, stretchy fabrics for comfort.

Ensure the tankini fits well around the bust, waist, and hips without digging in.

 

Try Before You Buy

Always try on different styles to see what feels best and flatters your body.
