“Best one piece I’ve ever tried,” the new mom wrote in a caption. “Usually it’s cut too low and the torso isn’t long enough - straps are adjustable. So comfortable! You nail it @sarafoster.”
She also shared photos of her stepdaughter’s family swimwear collection in “cotton candy sky,” which includes swim trunks for men and kids.
“Baby boy trunks for Rennie. The cutest,” Foster wrote in her own Instagram story, reposting her stepmom’s photo.
“Do we think @DavidFoster is gonna wear the trunks?” the designer captioned another pic.
McPhee shared another swimsuit selfie earlier this week in her Instagram story, embracing her postpartum body in a brown, high-waisted bikini.
“Loving my curves because my baby gave them to me,” she captioned the photo.
The new mom has been open about some difficult emotions she experienced as her body changed during pregnancy.
"Feeling like there was a relapse after getting pregnant was really shocking and upsetting and concerning for me, because I was suddenly so obsessed with food, starting from this first trimester, and I had such a distortion of the way that I looked,” she said during an interview on “Dr. Berlin’s Informed Pregnancy” podcast last month.
The "Smash" star revealed that she reached back out to the psychiatrist who had helped her through an earlier eating disorder, which she said helped ground her and give her a different perspective. By the end of her pregnancy, McPhee said she was much more at peace with her pregnancy body.
“I weathered it, and I’m just really grateful at the end of it that I feel this good,” she said on the podcast, which was recorded not long before she gave birth. “And that I look in the mirror and I’m like, ‘Yeah, my legs, my thighs, my arms are a little bit thicker, but I’m OK with it. I’m really OK with it.’”
