WOMEN'S breasts are getting bigger. One bra manufacturer, Berlei, reports the average bra size for Australian women is now somewhere between a 14C and 12D.

Berlei product manager Louise Woods said that just two decades ago 12B was the norm.

"Not only are women's boobs getting bigger but the number of women with a small back and a big bust is increasing. We are seeing more 10E and 12F and they are young girls," she said.
