Jill Zarin wasn't the only Real Housewives of New York City alum who showed up at last night's Bluemercury event. Carole Radziwill also hit the blue carpet to celebrate the beauty biz, and she looked cute and chic in a summery dress.

It made the outfit look like something you could wear to bike to a very chic brunch in the Hamptons. In other words, it was casual, spiffy, slightly preppy perfection. Carole's sun-streaked waves just added to the summery vibe.
