D85 Bra Size, In Full

A Japanese D85 is a 85 cm band with a D cup: written cup-first, measured in 2.5 cm steps, and one letter ahead of the Western alphabet. In US terms this body wears a 38C.

The trap

A Japanese D is not a Western D

Japanese cup labels start earlier and step in 2.5 cm increments, so each letter sits roughly one label ahead of its Western namesake: this D85 corresponds to a US 38C and EU 85C. Order your Japanese letter from a Western shop (or vice versa) and you’re a full cup off before the parcel ships. The converter translates in both directions.

Bands translate cleanly (same centimeters as EU labels); only the letters shift.

Japanese sisters move in 5 cm band steps with one cup letter, same volume, different circumference. Useful when domestic stock stops one band short of yours.

Construction

What works at this size

At this volume nearly every style in Japanese ranges works, and Japanese ranges lean heavily on molded, lightly padded cups with soft wires. Choose by neckline; construction rarely limits you here.

Answered

D85: answered

What is Japanese D85 in US sizing?

US 38C (UK 38C). Japanese cup letters sit one label ahead of Western ones for the same body (a Japanese D corresponds to a Western C-tier cup) so carrying the letter across unconverted buys a cup too big.

What measurements is D85 for?

An underbust around 85 cm (roughly 82.5–87.5 cm) and a top bust near 102.5 cm: a difference of about 17.5 cm, which Japanese sizing labels D. Japan measures in 2.5 cm cup steps against Europe's 2 cm, so conversions are nearest-label, not exact.

Why is the cup letter written first in D85?

Japanese convention writes cup-then-band. C70, not 70C. Same information, reversed order; on tags in Japan you may also see the band alone (70) with the cup on a separate line.
