Kourtney Kardashian In See-Through Underwear Flaunts 'Hottest' Body Of The Sisters

Kourtney Kardashian is turning heads in a new photo on Instagram as she promotes sister Kim Kardashian's SKIMS brand. The 45-year-old made headlines last week for featuring in Kim's new SKIMS x Dolce & Gabbana campaign, one promoting the two brands collaborating and featuring both siblings in one video. While the collab's debut came heavy on the leopard-prints, this week's photo showed Kourtney in a racier, see-through getup. Posing in a plunging, sheer two-piece the Poosh founder flaunted her killer curves, and it didn't take long for the compliments to roll in.

Scroll for the photo. Leaning forward to display her ample cleavage, Kourtney showed off her impressive figure in a strappy, skintight cami top covered in both the SKIMS and Dolce & Gabbana monogram. Flashing her abs and curvy hips, Kourtney added a minuscule pair of stringy briefs to match, upping the ante with her dark locks worn down.

Drawing the eye to tiny silver charms hanging on her briefs, Kourtney drove fans wild in black thigh-highs, sending out direct eye contact as she flaunted her good looks.

Wearing a heavy face of makeup that brought out her dark eyes, Kourtney wove her long-term relationship with Dolce & Gabbana into her caption, saying: "I got married in Italy."

Anyone remembering the 2022 headlines Kourtney made for marrying husband Travis Barker will know that the Italian designer sponsored the couple's wedding, held in Italy. "I have to say, their marketing is next level," one user replied. Noting that the slideshow had opened with a photo of both 44-year-old Kim and Kourtney, another fan said: "Second photo... The absolutely hottest body from any Kardashian."

Kourtney made November 2023 headlines for welcoming son Rocky. In the above photo, she cradled her son in a leggy t-shirt dress and boots getup, with a popular comment calling her the "coolest mom on the block." Kourtney also shares children Mason, Penelope, and Reign with ex-boyfriend Scott Disick.

"I think I take time for myself to work out every day," she told E! News. "Which I never did—especially having three young kids. I just never made it a priority, and now it makes me feel so much better—mentally and physically."

Kourtney looked fierce in this July photo, one coming as promo for her Lemme wellness brand.

"Meet our limited-edition Lemme Glow Lollipops! Made with Grass-fed Collagen, Vitamin C and Cocoa Butter, these pops are my favorite when looking for a sweet little treat, made right," she wrote. Kourtney founded Lemme in 2022 and is also founder of her Poosh lifestyle brand.
