"Hang in there, pregnant mamas! We got this."

Mark your calendars. On May 20, we're celebrating the birth of Levi's jeans. Well, it's not the exact birthday. But it's the day Levi's received a patent for the rivet pockets on the iconic 501 jeans, which you can find everywhere, from Macy's to Bloomingdale's. So each year the brand celebrates Levi's 501 Day on May 20. This year, marks the 145th birthday, so the brand is going all out, teaming up with celebrity stylist Karla Welch to create a limited-edition collection. Welch is the fashion pro behind the many A-lister outfits—like Amber Heard, and Karlie Kloss. Plus she's the founder of the x karla brand. The Levi's x karla collaboration is a denim lover's dream. You'll find two new versions of the celebrity-approved Levi's 501 jeans, a fringe trucker jacket, Western-inspired shirts, plus a cool pleated jean. “It’s all very customization focused,” says Welch. “I wanted to imagine what the future of vintage was. If people inhabit Mars 200 years from now, what are the kids going to wear? This idea of creating something that would eventually become an iconic piece of vintage clothing is the basis of the whole collection.” Naturally, the campaign is filled with all of Welch's celebrity friends—like Amber Valletta, Tracee Ellis Ross, and Yara Shahidi. Even InStyle's Editor in Chief Laura Brown makes a cameo. What's even more exciting? Levi's is making a donation to the Everytown for Gun Safety Support Fund in honor of the collection. Now, that's what I call a win-win. Catch your favorite celebrities in the campaign below. And get ready for the big day on May 20.

Money Talks, and so should we. Here, powerful women get real about their spending and saving habits.

One year has past since the historic Women’s Marches that filled city streets across the globe, becoming what's thought to be the largest single-day protest in U.S. history, on Jan. 21, 2017. And as we gear up for the second annual marches this weekend—and the start of a new voting initiative, #PowerToThePolls, kicking off in Nevada—we're looking back at what women's right activists have achieved between those bookends.  This week, the Women’s March organizers released Together We Rise, a narrative history of the making of the marches. Consider it a field guide for fighting injustice, punctuated with original essays from celebrities and activists like Rowan Blanchard, Ashley Judd, America Ferrera, Congresswoman Maxine Waters, Roxane Gay, and more. Judd recalls the nervous moments before the speech she gave at last year's march, which she opened with Nina Donovan’s poem “I Am a Nasty Woman.” Ferrera says the protest gave her hope for the future: “To move forward as a movement, we have to stay connected to the reason we marched in the first place: one another ... If we can bring that ethic of community and love into our daily lives, I believe we can sustain a movement beyond a single historical day.” Gay tackles internationality and addresses her reservations about mainstream feminism as a woman of color. RELATED: An Afternoon with the Badass Women Behind the Women's March There were plenty of other women who found the courage to speak their minds this year, too—and many of them put their rallying cries to paper, giving our library of feminist literature a fresh take. Head into the weekend with the most inspirational quotes from the best female-first books published since this time last year.
