InStyle's 2015 Style 100: The Year in Fashion Hits, Misses, and Hashtags

Sunshine State

Everything's coming up daffodils...and marigolds and buttercups. Shades of yellow—like those seen on Jennifer Hudson in Romona, Léa Seydoux in Prada, and Charlize Theron in Dior Haute Couture—made on irresistible bouquet of brights.

Peek-a-boo Dresses

The friendly competition to create the most naked red-carpet spectacle reached new highs (or lows?) at the Met Ball, where even Lady Godiva would have blushed. Beyoncé, in Givenchy Haute Couture by Riccardo Tisci, took it by a bugle bead, followed by Jennifer Lopez in Atelier Versace and Kim Kardashian in Roberto Cavalli by Peter Dundas.

High-Style Rollers

Imagine the stakes when Kristen Stewart and Julianne Moore were among the guest stars hitting the craps table at the Chanel Haute Couture show in Paris in July. I'll see your Twilight and raise you a Hunger Games.

A Fashion Festival at the Movies

Between two YSL biopics and docs about designers (Dior and I is a must), there were enough stylish films to fill a multiplex. Clockwise, from left: Iris, about 94-year-old fashion icon Iris Apfel; The Artist Is Absent, about Martin Margiela; Jeremy Scott: The People's Designer; Saint Laurent; Dior and I; and Yves Saint Laurent.

Double Take

An intentional face-plant was one way to draw attention in a roomful of famous folks, even when they didn't get the joke.

Blondes Do It Better...

A sign of the times? Kim Kardashian and Jared Leto went platinum on the same day.

...Or Do Brondes?

Has a better ring to it than babylights, right? Olivia Wilde wears this year's fave shade. Is it right for you?

All the Buzz

Newly shorn model Ruth Bell rocked the runways with military precision.

Bag Envy

The slimmest and subtlest It bag we've seen in years, Chloé's Drew owes its success to its versatility, its '70s flair, and its appeal to street-style stars everywhere ($1,850; nordstrom.com)

Prada's Sweets

Miuccia Prada's freighted foray into polite macaron pastels proved to be one of the most powerful runway statements of the year.

WHY, YOU DON'T LOOK A DAY OVER...

Fashion anniversaries are like birthdays: a cause for celebration. Designers marked milestones by collaborating with friends and reissuing classics. Among them (from left): Betsey Johnson’s golden jubilee of 50 years running was a runway tribute to Blondie, Nicki Minaj, Edie Sedgwick, and her own dance teacher. The best gift Giorgio Armani could give fans for the last 40 years was an update on his styles called the New Normal, and Brazilian jeweler H. Stern introduced galactic designs for its 70th anniversary, playing off the translation of its name ("star" in German).
