Demi Moore Waves In String Bikini On Boat Day

Looking classy and fit, Demi thrilled fans as she posed, waving from a boat and enjoying a day on the water.

Showing off her toned arms and shoulders, plus her super-flat stomach, Demi stripped down to a plunging black bikini, also going stringy and halter neck.

The ex to Ashton Kutcher kept her skimpy look chic via a black open shirt worn off-the-shoulder, but with a giant cleavage flash. Demi was upping the ante.

Smiling and confident, Demi wore her signature raven locks down and cascading down her back. A swipe surprised fans as Demi returned to lounging around her pool and showing off her killer figure in a plunging white bathing suit. Scroll for more swimwear after the snap.

In a caption shouting out her collab with popular brand Andie Swim, Demi wrote:

"Second drop is here! All styles in my collab with @andieswim are available to shop now 💗."

Demi had invested in Andie Swim prior to the global pandemic and as part of a $2 million seed round.

In a separate share and on its own IG, Andie Swim shouted out Demi, showing a photo of her in a black waffle swimsuit worn with a mean pair of shades.

"We want to see your Demi Moore x Andie looks! Take a pic in your new suit and tag @demimoore & @andieswim. Our faves will be reposted to our profiles!" the brand wrote, encouraging fans to share snaps of themselves in the collab's pieces.

The collab came heavy on the retro vibes and channeled Demi's love of swimwear styles dating back to the 1920s. The actress is not a giant fan of the micro bikini trend adored by the likes of SKIMS mogul Kim Kardashian.

Urging fans to pack their summer suitcases with Andie Swim, the company wrote: "Fall in love with these unique, vintage-inspired suits at the link in bio."
