Meta description: A complete guide to choosing the right MIDORI bikini top and bottom size for your body type, with our full XXS-XXL size chart and fit tips.

Quick answer

The right bikini fit comes down to matching support and coverage to your shape, not chasing a trend. Balance a fuller bust with a structured top and thinner straps for a smaller bust. Use a higher-rise bottom to smooth your midsection, and a smaller MIDORI size for a cheekier fit through the leg. MIDORI runs XS to XXL in tops and XXS to XXL in bottoms. The fastest way to find your fit is to compare your usual bra size and jean waist against our size chart below rather than guessing from your regular clothing size.

MIDORI size chart

Tops

Use your usual bra size as a starting point. Sizes intentionally overlap. Choose the smaller MIDORI size for less coverage or the larger size for more.

Need more room through the band? The adjustable Mia and Jesse tops accommodate select band sizes up to 40. An XXL Mia has worked well for customers in 34DDD and 32G, and an XXL Jesse has worked well for 40D. Contact us for personalized sizing help if you fall outside these ranges.

Bottoms

If you are between sizes, size up. It is the safer option and gives a little more coverage.

Shopping the Parker? It runs slightly roomier than our other bottoms, so size down for a more secure fit. If a bottom feels slightly too loose after your first swim, wash it once in warm water and tumble dry on normal. That tightens the fit by about half a size, then you can go back to your regular bikini care routine.

Bikini tops by bust size

Fuller bust (L-XXL, or 32DD and up) Look for a structured top with wide straps or built-in support, like our adjustable Mia or Jesse. Halter and crossback styles add lift without sacrificing comfort. A thin string triangle top without support tends to shift throughout the day at this size range.

Smaller bust (XS-S, or 32AA to 32C) Triangle tops and bralette styles work well. Push-up padding or ruched fabric adds shape if that's the look you want, but a simple cut in your true MIDORI size tends to look proportional without needing extra structure.

Broader shoulders or an athletic frame A halter or crossback top balances broader shoulders and keeps straps from sliding. If you're between sizes here, size up for comfort rather than down for a snugger look.

Bikini bottoms by body shape

Pear shape (fuller hips, smaller bust) Go by your jean waist measurement rather than your U.S. clothing size, since MIDORI bottoms are cut through the waist and hip. A higher-rise style smooths the waist, and if you're between two sizes on the chart, size up.

Apple shape (fuller midsection) A higher-rise bottom that sits above the belly button offers the most coverage and support. Match your size to your jean waist measurement first, then confirm against the U.S. size column.

Athletic shape (straighter waist and hip line) A cheekier cut or the Parker (sized down one from your usual MIDORI size) creates curve and visual definition through the leg.

Petite frame (XXS-XS) Our XXS starts at a U.S. 00 with a 22 in jean waist. If you fall below that, or between XXS and XS, contact us for personalized sizing help rather than guessing.

Common bikini fit mistakes to avoid

• Buying tops and bottoms in the same letter size without checking each chart separately, since bust and hip measurements rarely land on the same size
• Sizing bottoms by U.S. clothing size alone instead of confirming against your jean waist
• Forgetting the Parker runs roomier than other MIDORI bottoms
• Skipping the warm-wash trick when a bottom feels slightly loose after the first wear, instead of assuming the size is wrong

FAQ

What MIDORI top size should I choose if I'm between two sizes? Choose the smaller size for less coverage or the larger size for more. Our sizing intentionally overlaps by design, so either works. If you want the most secure fit, size up.

Does MIDORI bikini bottom sizing match my regular jean size? Not exactly, but your usual jean waist is a close second reference point. Compare it to the waist measurements on our size chart, which run from 22 in (XXS) to 33-34 in (XXL).

Why does the Parker fit differently than other MIDORI bottoms? The Parker runs slightly roomier through the cut. We recommend sizing down one size from your usual MIDORI bottom size for a more secure fit.

Can I shrink a MIDORI bikini bottom if it feels loose? Yes. Wash it once in warm water and tumble dry on normal. This tightens the fit by approximately half a size. After that, return to our standard bikini care routine to protect the fabric.

What if my measurements don't fit any size on the chart? Contact us with your usual size, preferred coverage, and the style you're considering. We offer personalized sizing help, especially for band sizes above 40 or bust sizes below 32AA.
