Carrie, 36, looked amazing in black bikini top which had ruffled detailing and a matching black sarong wrapped around her slim waist. She also wore black sandals and aviator sunglasses while keeping her blonde locks bulled back into a bun.
The star, who welcomed her second son, Jacob on January 23 with her husband Mike Fisher, has been working hard to get her pre-baby body back!
Carrie's hard work in the gym has certainly paid off — but she did admit in March that it's not always easy to bounce back!
The singer took to social media to post about the Calia sponsored event that her brand hosted in the Hamptons. "Had such an amazing time at the @CALIAbyCarrie Summer House yesterday with all our wonderful guests!!" she captioned the photo collage.
Carrie and her exclusive guests enjoyed their afternoon by the pool and participating in a class of yoga.
Later in the day, the American Idol alum and her team showcased Calia's new line of swimwear.
