Kim Kardashian Went Braless Underneath Her Single-Buttoned Cardigan

Another day, another controversial outfit worn by Kim Kardashian.

After visiting the Vatican in a lace dress with pelvic cut-outs, and the next day, pairing a silk minidress with a trucker hat, the reality star continued to document her Roman vacation looks on Instagram — and this time, she took on the sexy cardigan trend.

Posting a trio of photos to her grid, Kardashian went braless underneath a black ribbed cardigan that was secured by just a single button in the middle. She paired the sweater with a leather miniskirt, which featured a sequin dragon embroidered on the front, and sky-high stilettos. As a nod to the city's Catholic religion, Kim accessorized with a set of neon green cross earrings.

"Inches on the Roman Runway," Kim captioned the slideshow, referencing her pin-straight brunette strands that were equal in length to her super short skirt.

This week, Kim jetted off to Rome, where she not only visited the Vatican, but also another popular tourist destination: the Colosseum. There, she posed for photos wearing white keyhole cut-out top, silk shorts, high-heeled flip flops, and a colorful cross necklace.
