Birthday one-piece 1
Jenner was embodying a Baywatch babe for her 19th birthday. Notice something wrong with this picture? I do!
White robe 2
While most people only wear robes in the privacy of their own homes, the 19-year-old is just fine with rocking a similar style as a dress. Wow!
Green mini-dress 3
Jenner made sure to show off her assets in this silk olive-toned mini-dress. This looks like lingerie!
Low-cut black gown 5
Jenner has clearly taken some inspiration from her older sister, Kim Kardashian. She wore a daring low-cut black gown with a sexy slit on red carpet at Sugar Factory Miami.
Sheer white 6
While at Cannes in 2015, the teen turned heads in a sheer white skirt and crop top. Her mom, Kris Jenner, was also at the event and somehow didn't freak over this look!
Barely-there bathing suit 7
Don't count on Jenner to wear a simple bikini while working on her tan. She rocked this sexy cut-out swimsuit that looks way too mature for a then 17- year-old.
Striped mini dress 8
Jenner looked double her age in this dangerously short dress at the 2015 Billboard Music Awards. Talk about growing up too fast!
Burgundy high slit 9
Jenner looked like she stepped out in a sexy night gown during the 2014 American Music Awards. It's showing major cleavage and leg!
Pool party outfit 11
Kylie posed in this outfit with her then 24-year-old boyfriend Tyga and sister Khloe. Whoa!
All grey 12
Jenner looked super mature in this tight dress that pushes her cleavage and snatches her waist.
Purple bra 13
Wearing a sports bra as a top is one of Kylie's favorite trends. She would not be able to show up to any high school with this look!
Low-cut jumpsuit 14
Jenner was showing off major cleavage in this racy white jumpsuit. Her blue hair makes her stand out even more.
