As you can see, the 36-year-old looked on point as usual, despite the sheer fabric on her top exposing a little nipple. Also, please note that sister Khloe's bob is looking choice as hell right now.

The proud older sister was clearly having the most fun, as she went a little nuts with the Instagram posts congratulating Kendall on her big day.

Happy Birthday Kenya.💜

Aww, what a proud sister!

Kourtney has been killing it lately, after her split from longtime boyfriend Scott Disick in July. Despite their problems, Kourtney has been adamant about not keeping the couple's three children, 5-year-old Mason, 3-year-old Penelope and 10-month-old Reign, away from their father. Last week, the kids, along with grandma Kris Jenner, went to visit Scott in rehab, and even though Kourtney wasn't there, a source tells ET it was her idea.
