How to Take Your Measurements

Accurate measurements are key to getting the right body shape classification:

Bust: Measure at the fullest point of your bust. Do not squeeze the tape too tight - you should be able to breathe deeply.
Waist: Find the narrowest part of your torso, usually above your belly button and below your ribcage. Do not pull your stomach in.
Hips: Measure the widest point below your waist, typically around the fullest part of your buttocks.
High Hip: This is also a hip measurement, but taken at the top of the hip curve - not at its widest point. It is usually about 3-4 inches below your waist.

Understanding Body Shapes

Hourglass

An hourglass figure has bust and hip measurements that are nearly equal with a well-defined, narrower waist. This balanced silhouette looks great in almost any bikini style, from string bikinis to bandeau tops.

Top Hourglass

Similar to hourglass, but with a bust that is visibly larger than the hips. The key is finding swimwear that accentuates the waist while optically balancing the top and bottom halves.

Bottom Hourglass (Pear)

The pear shape has hips that are wider than the bust with a clearly defined waist. The goal is to add volume to the upper body while keeping the bottom simple and streamlined.

Spoon

A spoon shape has hips that are much wider than the bust with a shelf-like appearance. This body type benefits from styles that draw attention to the upper body and minimize the hip area.

Triangle

Triangle body types have a slim upper body with hips broader than the shoulders. The trick is to add volume to the upper body with ruffled or embellished tops.

Inverted Triangle

Inverted triangles have ample bust and shoulders with slim hips. Styles that accentuate the lower body and de-emphasize the bust work best.

Rectangle (Straight)

Rectangle body types are proportional but lack a defined waist. The key is to create the illusion of curves with ruffled tops, skirted bottoms, and strategic cutouts.

Bikini Shopping Tips

Wear whatever makes you feel confident: Our recommendations are guidelines, not rules. The most important thing is that you feel beautiful in what you wear.
Mix and match: Do not be afraid to buy different sizes for tops and bottoms. Many brands sell separates.
Consider your activities: If you plan to swim actively, choose more secure styles. For sunbathing, you can prioritize style over support.
Check the fabric: Look for quality materials with good stretch and recovery, like nylon-spandex blends.
Always use sunscreen: Protect your skin with proper SPF, regardless of your swimsuit style.

Frequently Asked Questions

How do I determine my body shape for a bikini?

Take four measurements: bust (fullest point), waist (narrowest part), hips (widest point below waist), and high hip (top of hip curve). Enter these into our bikini calculator to get your body shape classification and personalized style recommendations based on scientific body shape analysis.

What type of bikini should a pear shape wear?

Pear (bottom hourglass) shapes benefit from upper body enhancing tops with patterns, ruffles, and embellishments. Choose light-colored tops with darker, simpler bottoms. One-piece swimsuits with higher-cut legs and wide-set straps also work well. Avoid high-coverage bottoms that make hips appear wider.

Which body types look best with a high-waist bikini?

High-waisted bikini bottoms are incredibly flattering for women with long, proportional torsos. They create a horizontal line that can make the wearer appear shorter, which is great for balancing proportions. Rectangle shapes may find that high-waist bottoms emphasize their straightness, while curvier shapes can enhance their natural silhouette.

What types of bikinis look good on petite women?

Petite women look best in high-waisted, high-cut bottoms that elongate the legs, off-the-shoulder tops, one-shoulder tops, one-piece swimsuits with a high cut, deep v-cut necklines to visually add height, and vertical stripe patterns.

How should a plus-size woman choose a bikini?

Plus-size women should focus on fit and comfort first. Look for tops with wider straps and more coverage, high-waisted bottoms for tummy control, and supportive underwire or molded cup tops. Dark colors and strategic patterns can create a slimming effect. Most importantly, choose styles that make you feel confident and comfortable.

What is the most universally flattering bikini style?

The classic triangle bikini is one of the most universally flattering styles because it is highly adjustable. You can customize the fit by adjusting the neck and back ties. It works well for most body types, though the level of support may vary. For more support, look for triangle tops with thicker straps or underwire options.
