The reality star, 37, put on an incredibly cheeky display as she boarded a boat in Portofino, Italy.

Khloe rocked a daring Dolce & Gabbana mini dress which put her curves – and perky backside – on full show as she climbed onto the vessel.

The peekaboo dress also highlighted her toned midsection. She paired the look with a rust-toned pair of sky-high stiletto boots.

Warding off the springtime rays with a massive pair of gold-tinted shades, she added a splash of dazzle with hoops, a necklace and a luxurious gold bracelet.

Her wavy blond locks were teased into a do by Andrew Fitzsimons, while her makeup that day was applied by Ash Kholm.

Sauntering up to the front of the boat, she struck a pose for Instagram with her back to the camera so that her prominent behind was thrown into relief.

Dolce & Gabbana has apparently been a popular choice with the family during their latest jaunt to enjoy the delights of Italy.

The upcoming nuptials mark the third time Kourtney and Travis have said ‘I do.’

About a month ago, Kourtney had a drunken Las Vegas wedding with Travis, who shot to fame as the drummer for Blink-182.

After attending the Grammy Awards in Sin City together, the pair headed to a wedding chapel and exchanged vows in front of an Elvis impersonator.

However the ceremony was not legally binding as the couple neglected to obtain a marriage license beforehand, so further steps were necessary.

They sorted their civil marriage at a Santa Barbara courthouse this past Sunday and are now thought to be planning a sumptuous wedding this weekend in Italy.

The couple are reportedly planning to tie the knot at Castello Brown, a historic house museum located on a hill overlooking Portofino harbor.

Meanwhile Kris, who recently told People she has been ‘sworn to secrecy’ about the wedding, was also spotted strolling around Portofino on Friday.

While Kourtney’s three children Mason, 12, Penelope, nine, and Reign, seven, are in Portofino for the wedding, TMZ reports their father Scott Disick was not invited.
