Note to self: Intricate beading, high collars and feathers are classy; a suede, fringe-trimmed bikini top is not.

Fashionistas clashed this week when it came to style choices, as some glammed it up on the red carpet while others broke out the jorts and flower crowns for the annual Coachella festival in California. The dichotomy made it clear that while elegance never goes out of style, dressing like a hippie does.

Olivia Wilde

The 31-year-old actress looked fresh out of “The Great Gatsby” in a flapper-inspired Marchesa dress with Tiffany & Co. Blue Book Collection jewels and a Rauwolf clutch at the “Finding Neverland” premiere in NYC.

Dianna Agron

This belted Alexander McQueen gown was gleeful on actress Agron, as she prepares to present at the Olivier Awards at the Royal Opera House in London.

Keke Palmer

It’s all about the bump — the leg bump, that is. Palmer does her best Angelina Jolie impersonation in a revealing aqua Michael Costello gown at the “Brotherly Love” premiere in LA.

Amber Heard

Hello, Mrs. Depp! The newlywed stepped out for the Tiffany & Co. Blue Book Collection celebration in NYC in a sexy, rust-colored slip dress.

Alessandra Ambrosio

Is she stuck in the ’70s? The model and mother of two went for a risqué cowgirl theme in a fringe top and Daisy Duke shorts at the Forever 21 BBQ in La Quinta, Calif., during Coachella.

Padma Lakshmi

Party in the front — gray in the back? “Top Chef” host Lakshmi wears a head-scratching two-tone KaufmanFranco gown at EFA’s Annual Blossom Ball in NYC.

Cara Delevingne

What happened to our favorite bad girl? Delevingne skipped edgy and went for a prim and proper Reem Acra frock at the MTV Movie Awards at Nokia Theatre in LA.

Brooke Shields

This purple satin dress looks nothing but matronly on the statuesque Shields at the Tribeca Ball in NYC.
