Women's Dress Size Chart: US Sizes by Bust, Waist & Hips

A 36-28-38 is a US 8 — even though the hips alone fit a size 6. Your dress size is the largest size any one of your three measurements needs, so the bust and waist decide here, not the hips. Measure yourself, enter the three numbers below, and get your US size — or read the full chart from 0 to 20.

Dress size lookup — bust, waist & hips to US size

Dress sizes are not one measurement — they are three. Each of your measurements takes the smallest size whose chart value is at or above it, and your size is the largest of the three: a dress that fits your bust and waist but not your hips does not fit. The chart below is the standard US misses chart, sizes 0 to 20, the same chart as the site's waist-based dress size chart — cross-checked against Belk's published missy chart, which puts a size 8 at 36.5 in bust, 30 in waist, and 41 in low hip, so brands do vary. If any measurement falls in the next size, the lookup sizes up.

Your bust, measured around the fullest part, tape level and snug. The default is 36 inches.

Your waist, measured at the narrowest part of your torso. The default is 28 inches.

Your hips, measured around the widest part. The default is 38 inches.

Your dress sizeUS size 8.US size 8. Bust fits size 8, waist fits size 8, hips fit size 6 — so you take the largest, size 8.

Bust fits: Size 8

Waist fits: Size 8

Hips fit: Size 6

Chart row: 36 / 28 / 39 in (91.4 / 71.1 / 99.1 cm)

Your dress size is US 8. Bust fits size 8, waist fits size 8, hips fit size 6 — take the largest, size 8.

Exactly on a size, 34 / 26 / 37 in: US 4 — an exact chart match, no rounding.

Exactly on a size, 39 / 31 / 42 in: US 12 — an exact chart match, no rounding.

Exactly on a size, 42 / 34 / 45 in: US 16 — an exact chart match, no rounding.

Between sizes, 36.5 / 28.5 / 39.5 in: US 10 — every measurement falls between sizes 8 and 10, so you size up to 10.

Split sizes, 36 / 28 / 42 in: US 12 — the bust and waist fit size 8, but the hips need size 12, and the hips decide.

Outside the chart: below a 32 in bust, 24 in waist, or 35 in hips, or above a 46 in bust, 38 in waist, or 49 in hips, the lookup says so plainly instead of guessing.

How to measure yourself

Stand straight, breathe out naturally, and measure over light clothing with a soft tape — not a metal one. Bust: around the fullest part, keeping the tape level all the way around your back. Waist: at the narrowest part of your torso, usually an inch or two above your belly button — tip your body side to side and the tape will settle into the crease. Hips: around the widest part, usually at the fullest part of your seat, with your feet together. Measure each one twice; if the two readings disagree, measure a third time. A 36-28-38 is the default on this page and a common set of measurements — it takes a US 8, because the bust and waist both need an 8 even though the hips alone would fit a 6.

When your three measurements disagree

Most bodies are not one size. The rule on this page is to take the largest size any single measurement needs: a 36-28-42 takes a US 12, because the hips need a 12 even though the bust and waist fit an 8. That is the safe choice for a fitted dress, which cannot be let out at the hips — a dress that is too big at the bust can be taken in, but one that is too tight at the hips cannot be worn at all. For a loose or stretchy style, the rule relaxes: a knit dress with stretch can take the middle size, and an A-line skirt cares mostly about the waist. The branches on this page prove the rule: 34-26-37 is an exact US 4, 39-31-42 is an exact US 12, 42-34-45 is an exact US 16, and 36.5-28.5-39.5 falls between 8 and 10 on every measurement and sizes up to a 10.

Rounding convention, stated plainly: the lookup compares your measurements against the chart values exactly — a measurement equal to a chart value takes that size, and anything above it takes the next size up. Centimetres are inches times 2.54, rounded to one decimal, so 36 in is 91.4 cm and 28 in is 71.1 cm.

Who uses this

  • The online shopper: measures 36-28-38 and learns the answer is a US 8, not the 6 her hips alone suggest — and orders a dress that fits at the bust and waist too.
  • The between-sizes buyer: measures 36.5-28.5-39.5, sees every number falls between 8 and 10, and sizes up to a 10 instead of squeezing into an 8.
  • The split-size wearer: measures 36-28-42 and learns the hips decide — a US 12 — and stops ordering 8s that never fit at the hips.
  • The international shopper: reads the centimetre columns — 91.4 / 71.1 / 99.1 cm for a US 8 — and compares against a European or Asian chart without a second tool.

Accuracy & limitations

This chart is the standard US misses chart, sizes 0 to 20, the same chart as the site's waist-based dress size chart — and it is a guide, not a guarantee for every brand. Vanity sizing means brands routinely label the same body a different number: Belk's own missy chart puts a size 8 at 36.5 in bust, 30 in waist, and 41 in low hip, against this chart's 36 / 28 / 39, so a size 8 here can be sold as a 6 or a 10 elsewhere. Junior, petite, and plus lines cut the same numbers differently again, and a brand's own chart always wins over a general one — check the chart on the product page of the exact dress you are buying. The chart stops at US 20; bodies above a 46 in bust, 38 in waist, or 49 in hips are outside it. Fabric matters too: a stretch knit forgives a size, a structured bodice does not. Measure twice, and when between sizes, go up.

Frequently asked questions

What dress size is a 36-28-38?

US 8. The bust (36 in) needs a size 8 and the waist (28 in) needs a size 8, while the hips (38 in) alone would fit a size 6 — and your size is the largest any measurement needs, so the answer is 8.

What dress size is a 34-26-37?

US 4. All three measurements match the size 4 row exactly — 34 in bust, 26 in waist, 37 in hips — so there is no rounding and no sizing up.

What dress size is a 39-31-42?

US 12. All three measurements match the size 12 row exactly — 39 in bust, 31 in waist, 42 in hips — so the answer is a straight US 12.

What dress size is a 42-34-45?

US 16. All three measurements match the size 16 row exactly — 42 in bust, 34 in waist, 45 in hips — so the answer is a straight US 16.

What if my measurements fall between two sizes?

Size up to the next size. A 36.5-28.5-39.5 falls between sizes 8 and 10 on every measurement and takes a US 10 — a dress that is a little loose can be taken in, but one that is too tight cannot be worn.

What if my bust and hips are different sizes?

Take the larger one. A 36-28-42 is a US 12 because the hips need a 12, even though the bust and waist fit an 8. For a fitted dress the largest measurement always decides; for a loose or stretchy style you can sometimes take the middle size.

Why do two dress charts give different sizes for the same body?

Because brands size differently: Belk's missy chart puts a size 8 at 36.5 in bust, 30 in waist, and 41 in low hip, while the standard misses chart on this page puts it at 36 / 28 / 39. Vanity sizing moves the numbers further. Always check the chart on the product page of the exact dress you are buying.

How do I measure for a dress size?

Stand straight and measure over light clothing with a soft tape: bust around the fullest part, waist at the narrowest part of your torso, hips around the widest part with your feet together. Keep the tape level and snug, breathe out naturally, and measure each one twice.
