Bikini Top Size & Support Guide: Triangle vs. Bandeau vs. Balconette

Finding a bikini top that fits and stays put is easier when you know what each style offers. This guide explains triangle, bandeau, and balconette bikini tops, how to choose support and coverage, and how to build a matching set with the right bikini bottoms.

How To Choose Your Bikini Top

Start with how you want your swim top to feel. If you prefer adjustability and a classic V neckline, choose a triangle bikini top. If you want a clean strap optional neckline and minimal tan lines, try a bandeau bikini top. If you like a lifted, sculpted shape, go for a balconette bikini top. Measure at home, anchor the band first, then fine tune straps or ties for security.

Triangle Bikini Tops: Adjustable, Versatile Fit

Triangle tops are flexible and easy to customize. You can fine tune coverage by sliding the cups and adjust tension at the neck and back.

Try these triangle styles:

Fit tips: secure the back tie or closure first so the band sits flat, adjust the neck last for comfort and lift, and widen cups for more coverage or bring them closer for a skimpier look.

Bandeau Bikini Tops: Clean Neckline, Strap Optional

Bandeau bikini tops create a smooth, modern line and are great under cover ups or shirts. Add straps if you plan to be active.

Try this bandeau style:

Capri Bandeau Bikini Top in Gray

Fit tips: anchor the back tie or closure firmly, add optional straps for waves or activity, and look for double lined, seamless construction that keeps edges smooth.

Balconette Bikini Tops: Lifted, Sculpted Shape

Balconette bikini tops give a defined neckline and a supportive feel with adjustable straps.

Try these balconette styles:

Fit tips: let the band do most of the support, start straps on a looser setting and tighten gradually, and check the side profile for a smooth, contained fit.

Build Your Set: Bikini Bottoms That Match

Pick bottoms that complement your top and fit your preferred coverage.

Great matches:

Tie-side bikini bottoms for adjustability: Ibiza Tie-Side Bikini Bottoms in Black
Cheeky bikini bottoms for sleek lines: Bali Cheeky Bikini Bottoms in Black
Frill bikini bottoms for a feminine touch: Milos Frill Bikini Bottoms in Blush

Color And Set Building Tips

Monochrome sets always look polished: all black, all white, grey on grey, or champagne neutrals. For contrast, pair a white top with black bottoms, or mix champagne with white for a soft tonal look. If you want maximum versatility for a trip, choose a neutral top like black or grey that can mix with several bottoms.

How To Measure At Home

Measure underbust for your band size with a snug tape.
Measure around the fullest part of your bust without compressing.
Fit check: the band should feel secure first. If it rides up, tighten the back tie or closure, then adjust straps.

Care Tips So Your Fit Lasts

Rinse after wear, hand wash cold with gentle detergent, and lay flat to dry out of direct sun. Skip the dryer. Apply sunscreen before you suit up and let it absorb to protect the fabric.
