Kourtney Kardashian kicked off Throwback Thursday with a touching photo from her high school graduation.

In the shot that the Keeping Up With the Kardashians star shared on Instagram and her site, she rocks a long white dress with cap sleeves and her hair in a lob, clutches her diploma, and cradles a bouquet of flowers. Her late father, Robert Kardashian, stands proudly behind her with a smile and squeezes her arm, looking dapper with his hair slicked back, sporting a white blazer and a black shirt and pants.

"I remember my high school graduation so well!," Kardashian wrote in a post on her site. "I went to an all-girls Catholic high school with Kim. All of the seniors put a time capsule together and we buried something to remember each other by, with the plan to dig it up later. I wonder what happened to it. I haven't seen it since. We all looked like bridesmaids in the dresses we had to wear, but I still love these photos because my family all came together to celebrate my big day."

Kris Jenner also got in on Kardashian's graduation #TBT fun, posting a shot of her daughter smiling on that big day. "I remember this day!! You looked so beautiful @kourtneykardash! See all the pics from Kourtney's high school graduation on Kourtney's app. #family #memories #proudmama #love," she captioned it.

It was the second throwback shot Jenner shared Thursday, after she posted an adorable photo of Kim Kardashian West as a kid that showed the mom of two posing for a school photo in a uniform with a polka dot bow in her hair. "My little Kimberly! #TBT #family #love #throwback @kimkardashian," she captioned it. Total Minnie Mouse chic. The Kardashian-Jenner throwbacks just keep getting better every week.
