Kendall Jenner. No bra. See-through top and pants. Loves!

Young supermodel Kendall surprised photographers and travelers at LAX Thursday as she strolled into the international terminal in a see-through outfit with NO BRA -- nips on full display, underwear on view. Jenner was headed to the Cannes Film Festival in France and apparently she wanted to make a splash!

She's gotta compete with her pal Bella Hadid making out with fellow models on her Croisette balcony, grabbing Emily Ratajkowski's boobs, etc -- she had to think of something drastic ... and she did!
