CAT TELLS INSTYLE: "J'adore Dior!" exclaims the stylish host who wore a fitted black dress by John Galliano for Dior on last night's show. Deeley accessorized the sophisticated look with diamante bracelets ("all vintage finds from flea markets!"), a vintage broach in her hair ("it had a broken clasp, but with the right amount of bobby pins and a hope and a prayer, it remained intact for the entire show!"), and bejeweled T-strap sandals by Sergio Rossi. Her hair and makeup team, Sallie and Amy respectively, channeled Old Hollywood with a pinned-under bob created "as if by magic," says Deeley, and smoky eyes, red lips (Chanel lipstick in Vamp) and highlighter in all the right places. "Makeup that would make Ava Gardner green with envy."
