Decjuba Size Chart

Australian fashion · women's

Decjuba is an Australian brand using AU numeric sizing from 6 to 20, with a letter mapping where a 10 is Small, 12 is Medium and 14 is Large, and its chart is published in centimetres as ranges. A size 12 fits a 94–98cm bust, 75–79cm waist and 102–106cm hip. The most important thing to know about Decjuba is that fit is inconsistent across styles — there is no single run-small or run-large rule, so the same size can fit differently between a knit, a shirt and a tailored piece. Denim is the most variable and the most commonly called out, so check individual garment measurements before buying jeans. Decjuba publishes a full international conversion (AU 12 = US 8 = UK 12 = EU 40), with Australian and UK numbers identical. Because the chart gives ranges, sitting at the top of a band often means the next size up suits better. When buying secondhand, measure the garment flat rather than relying on the tag.

Decjuba uses AU numeric sizing (6–20) with an XXS–XXXL letter mapping. Its chart is published in centimetres as ranges per size.

How Decjuba fits

Decjuba fit is inconsistent across styles — there is no universal run-small or run-large rule, so the same size fits differently between knits, shirts and tailored pieces. Denim is the most variable; check per-garment measurements.

Decjuba sizing — frequently asked questions

Does Decjuba run true to size?

Not consistently. Decjuba fit varies across styles, with no single run-small or run-large rule, so the same labelled size can fit differently between a knit, a shirt and a tailored piece. Denim is the most variable and most commonly flagged, so check individual garment measurements before buying jeans.

What is a Decjuba size 12 in cm?

A Decjuba size 12 (Medium) fits a 94–98cm bust, 75–79cm waist and 102–106cm hip on the brand's centimetre chart, which is published as ranges. If you sit at the top of a band, the next size up may suit a tailored piece better.

Is Decjuba AU sizing the same as UK?

Yes — Decjuba maps Australian and UK women's numbers as identical, so an AU 12 is a UK 12. Its official conversion makes that a US 8 and an EU 40. When buying secondhand, measure the garment flat against the chart, since fit varies by style.

How to measure Decjuba against your own wardrobe

The most reliable way to check fit is to compare Decjuba's chart above to an item you already own. Lay it flat and measure in centimetres — see the full how-to-measure guide for step-by-step instructions.

Tops & dresses — measure flat, then double the bust, waist and hip figures for the full circumference.

Bottoms — measure flat, then double the waist and hip figures for the full circumference.

Dresses — lay flat with straps up, then double the chest, waist and hip figures for the full circumference.

Shoes — place the shoe on a flat surface or a sheet of paper, trace around the sole, then measure heel to toe in a straight line.
