Nike (M): Nike Is Launching Its First-Ever Maternity Collection

Each piece in the Nike (M) collection is designed to expand and contract with a woman’s body throughout pregnancy and the postpartum period. Data from more than 150,000 body scans of women helped the Nike design team understand exactly how the body grows and changes. That alone was a game changer for Wie West: “You don't have to try on outfits and be like, ‘Oh, is this a medium, does it fit me? Oh no, I have to wear a size large.’ Maybe it's dumb, but I don't like the feeling of not being able to fit in my clothes, not feeling like myself,” she says. “Having something that I know is the same size that I was before, mentally, that really helped me feel like myself.”

The capsule includes a nursing-friendly sports bra, tank top, and cover-up, and ultra-stretchy high-waist leggings.

“When I got into my seventh or eighth month, the leggings were what I lived in,” Morgan says. “When I was working out in shorts, sizing up was really awkward because I had to wear them extremely low with my belly. So the leggings came in handy.”

If Zolman had to pick a favorite piece, it would be the four-way-stretch tank top, which—unlike most maternity tops—doesn’t have any telltale ruching on the belly that screams, “I’m pregnant!” “When I first got it I was like, Okay, this is a normal tank top—I don’t understand how this is maternity,” Wie West says. “And then I wore it, and I was like, Oh, my God, this is amazing. The fabric just grows with you—it felt like it was my skin.”
