Rumer Willis showed off her trim figure in a barely-there black triangle bikini as she attended the opening weekend celebration at the Marquee Dayclub in Las Vegas on Saturday.

Rumer Willis’outfit was oddly paired with a very Vegas-style sparkling silver sequinned mini skirt and strappy black leather sandals.

The mismatching items made the outfit standout for all the wrong reasons, with Bruce Willis and Demi Moore’s daugheter better off sticking to one trend instead.

Meanwhile, Rumer Willis proudly displayed her freshly dyed ombre locks, which were brightly offset against her long black knit cover-up.

The 24-year-old finished off her bohemian style with a pair of vintage-inspired tortoise shell sunglasses and a delicate silver bracelet and ring combo.

Rumer Willis was beaming as she posed hand in hand in the sunshine next to her boyfriend, Jayson Blair, 28.

Jayson Blair, who stars in the NBC sitcom The New Normal, looked a bit less ready for a dip in a pink short-sleeved top, blue seersucker shorts and grey high top trainers.

Rumer Willis and Jayson Blair marked the opening weekend for the luxurious dayclub, which features infinity pools, in water private and ample dance space for those attracted to the popular DJ scene.

The poolside weekend is a welcome break for Rumer Willis, who just finished shooting the romantic comedy, There’s Always Woodstock, with Katey Sagal and Jason Ritter.

Rumer Willis will also be seen starring in this year’s drama, The Odd Way Home.
