Sonnet James, the California-based clothing company for playful moms, was founded by Whitney Lundeen, a mom of two boys who believes you should be able to look great without sacrificing your ability to run and play. The dresses are beautiful but durable—the kind of thing you could wear to a meeting or to the playground, then throw in the washing machine.

The Spring 2015 collection just launched, and you could live in these dresses all summer. Once the weather gets warmer, throwing on a dress feels so much easier than figuring out a full outfit—and they’re prettier than shorts:) All Sonnet James dresses are made in San Francisco, using fabric made in America.

Today Sonnet James is giving away dresses to five lucky readers. For a chance to win, please visit Sonnet James, and leave a comment below telling us your favorite dress. Five winners will be chosen at random tomorrow. Good luck! Update: The winners have been emailed. Thanks for playing!

BONUS for all readers: Get 20% off with the code CUPOFJO20. Good through March 26th. See the full collection here.
