The revealing outfit, which was designed by Kim Shui, featured navy blue embellishments and accentuated Kylie's curves in all the right places. She paired the one-piece with gold bangles and matching pointy-toe heels.
"Mega babe @kyliejenner in my lace jumpsuit for my show at #vfilesrunway," the designer captioned a pic of herself posing next to Kylie on Instagram.
Kylie (Starbucks in hand!) and her friends sat front row at the fashion show, while her on-again, off-again boyfriend, 26-year-old Tyga, took the stage to perform.
Last month, Kylie and her sister, Kendall Jenner, debuted their own ready-to-wear fashion line, Kendall + Kylie, and ET was at the launch party for their cute collection.
"It has been both of our dreams to be able to share our inspiration with our fans," Kylie explained. "There's a lot of range -- outfits you can wear every day, nighttime looks and some surprise statement pieces as well."
