Jessica Simpson smoldered in a plunging black swimsuit for her latest advertising campaign. The singer-turned-fashion-designer shot the entire campaign in the arid desert of Sedona, Arizona. She showed off her fabulous figure in the tiny black one-piece with fringe trim, according to E! Online.

The Southwest-inspired piece is from her eponymous label Jessica Simpson Collection from her spring/summer 2015 collection. The swimsuit Simpson wore will be available at Nordstrom stores and online. The campaign has been shot by renowned fashion photographer Gilles Bensimon. The styling department was handled by Simpson’s mother Tina, while her husband Eric Johnson accompanied her on the shoot.

In a photo shared on Instagram, the 34-year-old is decked in a black one-piece, standing in front of a rocky desert landscape. The hot mother of two is seen in her flawless complexion and robust blond locks. The star accessorized with hoop earrings, lots of bangles and rings.

The picture also shows her toned legs, arms and slim figure, with the “Jessica Simpson” logo scrawled across her legs. The fashion designer and entrepreneur said the collection was “influenced by the Southwest -- turquoise jewelry, worn denim, and tons of suede and fringe.”

The Jessica Simpson Collection’s spring-summer 2015 line has been named “Sedona.” “I’ve always been inspired by the Southwest. For our Spring 2015 campaign, my team and I packed our bags and hit the dusty trail, traveling eight hours -- by tour bus -- from Los Angeles to Sedona, Arizona,” she wrote on her website.
