Better nutrition is causing the chests of women in China to grow larger, forcing bra companies to make larger cup sizes.

Triumph brand saleswoman Zhang Jing tells the Shanghai Daily, "It's so different from the past when most young women would wear A- or B- cup bras... You never expect thin women to have such nice figures if they are not plastic."

Reuters, citing the Daily's Web site, says lingerie company Embry Group has discontinued making A-cups for bigger chest circumferences.

Increased demand has caused the firm to step up production of C-, D- and E- cup bras.
