The Natori Size Chart, Interactive

Natori grades a premium US chart (A to DDD on 30 to 40) famous for its stretch-lace upper cups, which quietly forgive a half-size of top-cup error in either direction.

Reading it

How Natori sizing reads

Natori’s chart reads band-then-cup in inches and US letters: the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation.

How Natori runs

BandBands run soft or stretchy: many wearers take a band down and a cup up to keep the volume.

CupCups grade small: try your measured cup and one up.

Wire & strapsWires are average width for the system. Straps: Fine, decorative straps on many styles.

Quirk 1Cups grade small above D: many wearers go up a cup from their measured size

Quirk 2Bands are stretchy; a snugger band with a larger cup often fits better

Quirk 3Range narrows sharply above DDD

Honest edges

Where this chart ends

Beyond DDD, Fantasie and Panache continue in UK letters. And if a symptom (riding band, gaping cup, poking wire) sent you size-hunting, the fix guides decode it before you spend anything.

Answered

Natori sizing: answered

Does Natori run true to size?

Band: Bands run soft or stretchy: many wearers take a band down and a cup up to keep the volume. Cup: Cups grade small: try your measured cup and one up. In one line: bands run soft here: if you're between sizes or want firmer anchoring, try your snugger sister (band down, cup up); cups grade small: start at your measured letter and have one up in the fitting room.

What sizing system does Natori use?

Native US sizing (it reads band-then-cup in inches and US letters) the alphabet doubles after D (DD, DDD) before jumping to G. Your measured US size maps straight onto this chart with no letter translation. The interactive chart above shows every size with its US, UK, EU and FR equivalents.

What sizes does Natori carry?

30–40 bands with A–DDD cups in US notation. 36 sizes in the core chart. Select styles reach G and a 42 band.

What if Natori doesn't make my size?

Beyond DDD, Fantasie and Panache continue in UK letters. Sister sizes (same volume, different band) sometimes bridge a one-band gap: the calculator above tries them automatically before giving up.
