With the summer movie premiere season in full swing, stylish starlets, from Cameron Diaz to Liv Tyler, have been walking the red carpet and showing off the season’s trends. Have a look.

Valentino dresses have seem to be popping up more and more often on the stylish set, so it should come as no surprise that

Keira Knightley

would choose a bird-embellished dress from Valentino’s fall 2014 collection for the “Begin Again” premiere held in New York in June.

Tyler is making her way back into the limelight with her role in the new HBO drama series “The Leftovers.”

She showed up at the premiere in June in a pre-fall 2014 Stella McCartney fringe number that showed off her signature sleek-with-a-hint-of-edge style in black and blue.

Diaz arrived at the LA premiere of

“Sex Tape”

on July 10 in a spring 2015 Stella McCartney polka-dot number that perfectly combined playful and sexy into one outfit. Would you expect anything else from Diaz?

Diaz went to all out “sexy” in a shimmery white one-shoulder Roland Mouret for the Barcelona premiere in June.

Young up-and-comer

, Nicola Peltz must be taking cues from her fellow actresses, because she also chose a simple white Stella McCartney gown for the Berlin premiere of

“Transformers: Age of Extinction”

in June.

Keri Russell looked prim and proper wearing Resort 2015 Monique Lhuillier at the

“Dawn of the Planet of the Apes”

premiere in San Francisco in June.

Then on July 8, Russell added some edge in an all-black outfit (including a sheer top) for the New York premiere.

On July 14,

Kate Hudson’s

glitzy sequin cut-out Michael Kors dress was the talk of the town (and the Internet) after she posed for pictures at the “Wish I Was Here” New York premiere.
