It’s Breast Cancer Awareness Month — Do You Know What to Look For?

Munn shared with TODAYthat she didn't initially plan to show her scars on the set. The campaign was focused on her recovery post-breast cancer diagnosis, but the makeup artist had a hard time covering up the scars throughout the shoot. She explained that she took a look in the mirror and thought, "I’m done being insecure about my scars." From there, she took the idea to show them off to the SKIMS team — and the rest is history.

And while she was scared to be so vulnerable on camera, this was ultimately a really empowering move for Munn. She elaborated that there are "so many women that have these same scars" who feel just as insecure as she did about them — and she really hopes those women see this ad. "Skims is so iconic and associated with beauty and sex appeal, and cancer really doesn't have that same connotation," she said. "So I just really hope that other women who have gone through my same path feel a little better after seeing it."

The star also took to Instagram to give a behind-the-scenes explanation of her experience. She reiterated that she was "done being insecure" about her scars. "Every mark life has left behind on my body is proof of how hard I fought," she wrote. "I hope other women who have been self-conscious about their scars see these photos and feel all the love I’m sending."

She also shared that SKIMS will donate 10% of their bra sales (except bralettes) to Susan G. Komen® — a charity dedicated to finding a cure for breast cancer — from October 23-31 in stores and online. "It’s really meaningful to be part of an initiative that supports research and helps countless individuals impacted by breast cancer," she said.

All of this comes on the heels of Munn's announcement earlier this year that she was diagnosed with breast cancer. She revealed the diagnosis came after recently tested negatively for well-known breast cancer genes and had normal results from her annual mammogram — but her doctor to check her Breast Cancer Risk Assessment Score. The test showed Munn had a 37% risk of breast cancer, so she pushed for more answers that eventually lead to her diagnosis.

Since then, Munn shared with PEOPLE that she had 4 surgeries in 10 months and underwent medically-induced menopause — all the while juggling being a new mom with husband John Mulaney. She shared, "I'm lucky. We caught it with enough time that I had options. I want the same for any woman who might have to face this one day."

After that March announcement, it's clear Munn is dedicated to raising awareness for women's health — and particularly their options. While chatting about the SKIMS campaign, Munn told TODAY, "You've got to go your doctor and you inundate them with information and you don't stop until they give you the test you need."

If you want to test your own risk for breast cancer, the National Institute of Health has resources here.

But even Larson has days she feels off, saying she knows that feeling "very well," and whether it's seasonal blues or mental health days, she knows routine is where she thrives — and seasonal affective disorder lamps. "Light is a big game changer for me because I grew up in California," she says.

To engage her other senses, she relies on movement, breathing techniques, and temperature changes to keep in touch with her body. "A hot bath, a cold shower, both — anything that sort of wakes your brain up and kind of jolts it," she says. "I have a pretty demanding schedule and I truly don't have room to not feel like I'm present in my life. And so you come up with ways to figure out how to do that."

That includes everything from drinking plenty of water and prioritizing sleep to packing foam rollers and bands in her carry on. "It looks like a clown bag!" she says. "I always do [those exercises] every morning because even if I don't want to do it, which I always don't want to do it, I feel a lot better after I do it."

Admittedly, that's exactly how I feel some days about making breakfast — but a powerhouse like Larson knows how important fueling our bodies is. "Pretty consistently I'm having an egg, like a breakfast sandwich, egg on toast first thing in the morning," she says. "I can't think beyond that for breakfast because I wake up so early. It's like there's no creativity happening in the morning. I'm sorry. No."

And while her mornings are all about wellness, her evenings are all about getting cozy, and she tells me her dream night in includes playing a new video game, wearing Gelato Pique sweatpants, and ordering Thai food. But when she's in the kitchen? "I've been making pasta and sausage quite a bit and I make tacos quite a bit. I mean, I kind of just do like protein and veggies and a little bit of a carb," she says.

Cozy nights in wouldn't be the same without a movie, and there's a very good chance you've seen Larson on your screen recently, whether you're rewatching Captain Marvel, 13 Going on 30, or Lessons in Chemistry. But how does the actress consistently choose such beautiful, inspiring pieces to work on? She equates the feeling to having a crush.

"When I feel like [a story] hits something that lives so truthfully in me that I just want to know if it's true to other people," she says. "I just know that we all have more that's the same than different...Film and television, it lives in a way that is beyond me physically. So I'm here talking to you, but anybody can be watching whatever they want. And so I try my best to think through what the pieces are saying so that they go out in the world and I don't get to be at the end of it and explain it or tell people what to feel or what to take from it. It lives a life outside of me. So I try and make sure that it has a complete message in it that I feel like I'll be able to live with for the rest of my life."

Just like Carol Danvers and Elizabeth Zott empower so many viewers, Brie Larson says she feels empowered by her own Hollywood heroes. "Earlier in my career, like when I was trying to visualize what kind of career I wanted, it was Toni Colette and she's still a hero of mine, but she was truly the one that I was like, 'I want to disappear into characters the way she does.'"

"There's so many incredible [actors]," she continues. "Some of them are people that are more my age and some are older than me. But that's the fun part of my job is that there's so many good people and so many things that are getting made. And so it just feels like we're constantly kind of maneuvering, and when they take on certain roles and represent certain things, it frees up for other people to do other things. And so we kind of all work as a unit."

One movie on the horizon that I'm excited for is Mattel's new American Girl movie. Like many 80s and 90s kids, Brie Larson loved American Girl dolls — and borrowed her stage name from pioneer Kirsten Larson! And just like the rest of us AG kids, she tells me she can't wait for the movie. "I've also seen that there's going to be adult Halloween costumes, which I'm also very excited about," she says. Will she be grabbing a Kirsten one for herself? "I just might!"

Q+A With Brie Larson

What's the first thing you did after you won your Oscar?

I probably drank champagne...I drank champagne and I put sneakers on, and then I went to the airport.

What's the best piece of advice you've received?

"When I think I know, I miss so much." We all get stuck in these things — I think an easy one to think about is like, you're in a fight with your sibling or your partner, and you are just so right in how angry you are. And then maybe the next day you wake up and you're like, "Maybe there was another side to that." And so we miss things when we're in a space where we believe that we know. Having an openness to what something can be or that things can be different than what you think makes things easier.

What's on your holiday bucket list?

I love the holidays. Because I'm in California, I really am looking forward to this year having a chilly winter. I love a cold winter, cozy winter. I love Christmas markets, so I'll definitely hit things like that. All the little holiday markets pop up around, yeah, it's just like a rare time when everybody is resting at the same time.

What are you watching, reading and listening to right now?

Okay. I am reading a book called Patricia Wants To Cuddle. I am watching Love is Blind season 7 because I am not silly. And listening to Chappell Roan, obviously.
