Jennifer Aniston.

Byline: KATE SULLIVAN

Oh, this old thing? Jennifer Aniston just threw it onand managed to make it look completely perfect. At least that's the vibe you get from her, even at events that require maximum primping. Aniston never seems to overdo it. With a floor-length powder blue gown, skimpy sandals make her look almost beach-bound at a film premiere. A low neckline, flared pants, and her bright smile turn a refined tuxedo into an outfit as laid-back as pajamas. In a tight, strapless minidress, she doesn't look trussed-up or suffocated. Simply put, Aniston breathes easy.

By Heart

Diamonds are a standard red-carpet choice, but both for events and on her own time, Jennifer Aniston chooses jewelry closer to her heart (pun intended). She regularly wears long, classic gold chains, but among them is a pendant shaped like a human heartand it's anatomically explicit, complete with valves and arteries. The necklace, by London designer Solange Azagury-Partridge (whose first piece was her own engagement ring), gives Aniston her own kind of quirk.
