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.
