Yael is all about pieces that can multi-task. "Every girl needs a good ballet flat and a good men's style loafer. This is both!" Yael says of the Rochas flats ($280) at left. "A long slip-dress( $270) is seasonless and can go from casual to dressed-up by a simple shoe change."
Other pieces on her must-have list? An Yves Saint-Laurent snakeskin clutch, $2,200; a gold sun cuff by Pamela Love, $425; arrow earrings by Bing Bang, $111; and a pair of round-frame sunglasses from The Row, $440.
