Kendall's 21st Birthday in 2016
The model's LaBourjoisie mini was meant to show off Kendall's figure from all angles. The halter dress had a very low neckline, slits on the side, and an open scoop back. The outfit might not look like's made of much fabric, but the $9,000 gown took seven days to make and resembled the dress Paris Hilton wore for her own 21st birthday. It was a glittery, sexy number for a birthday celebration.
