Lauren Sanchez, 55, emerged for the evening in a stunning pink embellished bandeau gown, believed to be by Atelier Versace, that enhanced her ample assets – a very different look than her modest wedding dress. She wore her raven tresses in a side-part and accessorized with small and subtle earrings

Groom Jeff Bezos, 61, wasn’t exactly on theme for his ‘pajama party.’ But the billionaire tech mogul seemed excited nonetheless, wearing an all-black look featuring a blazer and button-down top. He finished the look with black aviator sunglasses

Kendall Jenner, 29, was spotted earlier in the day flashing her midriff but changed into an all-blue blazer-inspired ensemble for the evening. She topped with a mesh scarf over her head that flowed down her torso

Oprah Winfrey, 71, showed up in a chic, silk brown co-ord that boasted fringe sleeves. The TV personality wore her hair down in lose curls and hid behind a pair of shades as she waved to adoring fans

Leonardo DiCaprio’s girlfriend Vittoria Ceretti, 27, was seen leaving Gritti Palace Hotel wearing a sheer dress that boasted a series of unusual embellishments. She wore her hair down and paired the look with a subtle, but beautiful necklace

It’s no surprise that even when the theme is apparently ‘pajama party,’ Kim Kardashian, 44, showed up wearing a corset-inspired look. Kim channeled her inner Victoria’s Secret angel as the tulle, sheer tights and garters gave it a lingerie feel

Kylie Jenner, 27, pushed the limits with a fringe V-shaped crop top that barely covered her chest. She fought against a potential fashion mishap by seemingly using pasties to cover her nipples. She then paired the look with a simple white mini skirt (and a glass of wine)

Ivanka Trump, 43, opted for an all-black mini dress that boasted sequin detailing and a scalloped hem. The mom-of-three wore her blonde tresses in loose waves and added a pop of color with a slick of red lipstick

The matriarch of the Kardashian-Jenner clan, Kris Jenner, 69, appeared on the third day of wedding festivities channeling her inner Cruella de Vil in a black and white ensemble. Her look featured a black fringe trim over a white coat with small circle cut outs. She matched the look with sleek sunglasses and drop down earrings

Leonardo DiCaprio, 50, attended yet another one of the Bezos and Sanchez events with a baseball hat shielding his entire face from the paparazzi. He also wore a black overcoat and silk purple button-down shirt inside. DiCaprio has been hiding his face from pictures for quite some time now for some mysterious reason

Brooks Nader, 28, opted for a more risque look, donning a black off-the-shoulder one-piece corset and a mesh, lace asymmetrical skirt with a slit. The model paired the sleek look with a high ponytail, silver earrings, and a black clutch

Film producer Brian Grazer, 73, seemed extremely excited to be part of the festivities as he joined the third day of the Bezos and Sanchez wedding in Venice. He arrived – probably one of the only guests on theme – in a leopard print matching set
