Lest there be any doubt that Summer is in full gear (though technically the season doesn't arrive until June 21), Lupita Nyong'o is here to remind you that nothing but sunny days are ahead. Donning a Fausto Puglisi  mini, the star doubled down on warm-weather references with a teal hue and palm-tree print.
Joining her in that spirit, Kerry Washington, Sarah Jessica Parker , and Allison Williams dressed for the month in brights, pastels, and white. See all the looks we loved on some very chic ladies.
At the Maui Film Festival, you couldn't (nor shouldn't!) miss Lupita Nyong'o's Fausto Puglisi  dress, thanks to a teal hue and festive palm-tree print.
Still, you don't have to wear color to be seasonal. Allison Williams embraced the weather in her white lace Dolce & Gabbana  gown.
There may have only been a whisper of blush, but Nicole Kidman 's Prada  gown screamed "Summer" at the Melbourne Life Ball.
At the Young Friends of Acria Summer Soiree, Jaime King skipped Summer altogether and went straight to Fall in Jason Wu's fresh-off-the-runway  look.
Diane Kruger  ensured her Nina Ricci  dress spoke to the warm weather by pairing it with hot pink heels at the Chrysalis Butterfly Ball.
Jessica Biel  looked fresh in Giambattista Valli 's airy design at Tiffany's Paris bash.
Kerry Washington returned to the red carpet on a bright note when she attended the Women in Film 2014 Crystal + Lucy Awards in Sportmax 's splattered cocktail dress.
Sarah Jessica Parker
At the amfAR Inspiration Gala, the only thing springier than the off-the-shoulder silhouette of Sarah Jessica Parker 's Schiaparelli Haute Couture gown was its pretty pastel print.
Though Emmy Rossum's icy tone might say Winter to some, we were feeling a serious Summer vibe from her Ralph Lauren  Collection gown's halter neck.
Black can look just as seasonal, as Jessica Alba  proved at the Spike TV Guys Choice Awards. Sheer panels gave her David Koma  sheath the warm-weather treatment.
