Double tap! Kylie Jenner is all grown up and showing off her crazy curves on Instagram.
Wearing a sexy Balmain LBD, which accentuated her tiny waist and ample cleavage, the KUWTK star channeled older sister Kim Kardashian in the designer ensemble.
Paired with strappy black heels, the 19-year-old made the sidewalk her runway.
The brunette beauty has been showing off her noticeably larger butt on social media, especially during her birthday getaway to the Turks and Caicos.
However, don't be fooled! Kylie credits her newfound curves to Spanx.
