She doesn't strike us as someone that would worry about flashing a little underboob!

Kylie Jenner accompanied designer pal Olivier Rousteing to the Marie Claire's Image Maker Awards last night in West Hollywood, and the reality star donned a skimpy bright purple Balmain dress that showed off her butt, boobs, and everything in between! While we like the color, the cut of this frock reminds us of an ice skating outfit.

The plastic surgery princess brought along boyfriend Tyga as her date, and they hit Catch restaurant for the after party. We wonder how Cindy Crawford, who was also at the bash, felt about rubbing elbows with the LipKit mogul? The supermodel sure showed the 19-year-old a thing or two about dressing classy without looking trashy.

T-Raww seems to prefer his lady love even more undressed than she was last night, as he took to Instagram to share some PDA-packed photos of the couple from their recent trip to Mexico. Caliente!
