Star Must-Have Layering Pieces

Savvy celebrities play favorites, reaching for the same layering piece over and over again. Learn the secrets behind the versatile must-haves of stars like Olivia Palermo, Alexa Chung and Jessica Alba!

Layering pro Olivia Palermo knows the power of a plush vest. The fashionable star used a black fur version to pull together a mixed print outfit (left), to complement luxe leather leggings (center) and to (literally) warm up a delicate dress and fringe top.

DJ Alexa Chung definitely has a signature! She layers a button-down under a pretty dress to give it a little tomboy style. Bonus: This is a great way to add coverage to a too-skimpy dress.

Busy mom/businesswoman Jessica Alba uses a denim vest to contend with playground-to-office climate changes. She slipped one over a plain tee for a day of errands (left), popped it on top of a '80s-inspired sweatshirt for a retro look (center) and used to edge out a pretty maxidress (right).

With her trans-Atlantic lifestyle (she moves between Los Angeles and London), Kate Hudson has become a master of sporting that most versatile of pieces-the scarf. She wore a striped wrap for a long flight (got to battle that airplane A/C!), chose a C.Eaton & Co. scarf to add color to a sultry LBD, and tied a geometric print version around her neck to dress up a classic trench.

Miranda Kerr makes the most of her denim shirt by using as a toss-on jacket and wearing it buttoned-up under sweaters.

Whether she is wearing a gown or simple separates, Rashida Jones inevitable tops off her look with a masculine-inspired navy or black blazer. Smart lady! This trademark makes even the wildest prints totally wearable.
