Birchbox, a pioneer in selling monthly subscription boxes filled with beauty samples, is partnering with Reese Witherspoon to celebrate Women's History Month with its March box.

Draper James is Witherspoon's Southern-inspired lifestyle brand. The March Birchbox is decorated using one of Draper James' pretty print patterns.

The box's theme is "Pretty Mighty," and includes five deluxe "power beauty" samples: Benefit Cosmetics The POREfessional Face Primer, R+Co Dallas Thickening Spray, Clarins Hydra Essential Silky Cream for a luxurious dose of SPF, ARROW Boost Color Enhancing Lip Balm, and Davines OI All in One Milk plus OI Shampoo + Conditioner.

"We are so excited to team up with Birchbox, another dynamic, female-founded company, to celebrate Women's History Month," said Reese Witherspoon. "We had a lot of fun putting the box together to honor all of us - mothers, sisters, friends, daughters and coworkers - as the powerful women that we are."

New subscribers signing up by March 24th have the option to receive this box as their first, and current subscribers have the option of choosing it in place of their regular assortment of personalized samples.

Katia Beauchamp, Birchbox cofounder and CEO, says, "We built Birchbox to make it easier and more fun for busy women to discover beauty. That mission drives us every day, but March is an especially important time for us to honor, support and empower women. Reese Witherspoon is an inspiration and role model to all of us; she is a multi-talented badass and founder of Draper James, a brand we love because it embodies a confident and feminine woman. We're so proud to partner with them  to celebrate our pretty mighty customers."

Another Limited Edition 'Power Beauty' Box

In addition to the subscription, customers can also purchase a limited-edition Birchbox + Draper James box filled with multi-tasking, powerhouse products -- the "Power Beauty" box. It features a mix of full-size and travel-size beauty essentials, plus two exclusive lifestyle items from Draper James - a large, gold-accented makeup pouch for on-the-go touch-ups and a trinket tray.

The beauty products include a luxe treatment gel from Sunday Riley that transforms into a toner, a hydrating lipstick by Lipstick Queen in a works-with-everything red, a Ouai Treatment Mask, Living Proof Restore Instant Protection and Smashbox Indecent Exposure Mascara, among others.

This box launches on March 6 and will retail for $58 exclusively at Birchbox.com and the Birchbox Soho store.
