Up-and-coming model Kendall Jenner outshone her sister Kim Kardashian in an Azzedine Alaia dress she borrowed from Kardashian to attend the Hunger Games premiere.

Jenner looked so amazing that the 31-year-old reality star couldn't resist blogging about how gorgeous her 16-year-old sister looked in the dress.

Kendall borrowed my Azzedine Alaia dress last night for the Hunger Games premiere! Kardashian wrote. Doesn't she look gorgeous!! It's such an amazing dress!

Kardashian explained that she got the dress while in Paris with her mom in 2010 when she met the designer himself.

The dress is a sleeveless black- and-white number and Kardashian wore it while celebrating the season finale of E!'s The Spin Crowd back in October 2010. While Kardashian wore the dress with black tights and an oversized belt, Jenner showed off her long legs/

I remember I always used to try on my mom's Alaia dresses when I was younger, so I'm glad I have younger sisters I can share my favorite pieces with, Kardashian wrote.
