Bikini Size Guide: How to Measure and Choose Your Fit
Quick answer: Measure your bust, underbust, waist and hips, compare them with the current Midori size chart, then read the fit note for your chosen style. Choose top and bottom sizes separately. A secure fit should stay close without painful digging or strained fabric.
How to measure for a bikini
Use a flexible measuring tape and keep it level. Measure close to your body without pulling tight or holding your breath. Ask someone to help check that the tape is straight if needed.
- Bust: measure around the fullest part of your bust.
- Underbust: measure around your ribcage directly below your bust.
- Waist: measure around your natural waist.
- Hips: measure around the fullest part of your hips and seat.
Compare your measurements with the current Midori Fit Guide. Use that chart for size numbers rather than an older blog or another brand's chart.
Choose your top size independently
Your bra size can help describe your fit, but it does not translate perfectly into every bikini size. Compare bust and underbust together and check the product's coverage and adjustability. The band should remain level when you raise your arms, and the neckline should not spill or gape.

Choose your bottom size and coverage
Hip measurements give you a starting size; cut and preferred rise affect how it sits. Cruz has thong coverage. Kai has skimpy coverage, thin sides and a scrunch back. Brayden has cheeky coverage, wider bands and a scrunch back. Parker has moderate coverage, a low rise, thin sides and a smooth back.
Parker fit note: Parker runs slightly larger. Follow the product's recommendation to size down for a more secure fit, especially if you are between sizes.
What to do when you are between sizes
Use the individual style note first. Check which measurement is placing you between sizes and whether you prefer more or less coverage. Do not size down solely to force a tight fit. If you are unsure, contact Midori with your measurements and the styles you are considering.
Check the fit at home
Follow the try-on and return instructions. Raise your arms, sit and bend gently. The top should stay in place and the bottom should sit smoothly without rolling, gaping or uncomfortable pressure. A different cut can help when changing sizes does not.
Frequently asked questions
Do I need the same top and bottom size?
No. Midori sells separates so you can size each piece independently.
Should a bikini feel tight?
It should feel secure and comfortable. Painful digging, restricted movement and overstretched fabric suggest a fit problem.
Can I use my clothing size?
Treat it as a rough starting point. Measurements and the current brand chart are more useful.
