In that blue button-down blouse, red skirt and white bra, Nicole is the true Supergirl, not that other chick from Krypton. Now, about her bras..Nicole buys different brands in different sizes. "I've got quite a narrow back," Nicole says. "I'm a 32 to 34 around the back. In cup sizes, I can wear a double F or a G. It varies from bra to bra depending upon the designer." The sizes Nicole mentions are British sizes, not North American.
