See the below image for the Womens size conversion diagram. Women’s dresses, clothing, blouses, shirts and sweater’s size conversion charts between American (US), Canadian, European, British (UK), Australian, Italian, French and Japanese sizes. There are two charts (women’s and junior’s) for women’s dress sizes since United States use different numbering system (even vs odd) for each category.
Girls’ sizes are far less curvaceous than women’s, based on the expectation of developing, not developed, bodies. Outside of plus sizing, slender limbs may also be assumed. Size charts for girls’ clothing will not list a bust measurement, but instead a chest measurement. Some clothing charts do not address the chest area at all.
For many brands, a women’s size 0 or XS features a bust size of about 32 inches, a waist size of about 25 inches and a hip size of about 35 inches. In juniors’, this is similar to a size 3. In girls’, these measurements may correspond most closely to anywhere from a size 14 to a size 18, depending on the brand.
