Alix Earle shows off two-piece red outfit while celebrating sister Ashtin's graduation

Leave it to Alix Earle to not only look fabulous but do it for a good cause. Alix was in attendance with her boyfriend, NFL player Braxton Berrios, when her sister Ashtin graduated from Tulane University over the weekend.

Earle headed over to her Instagram account on Sunday, May 18, and dropped a photo bomb from Ashtin's big day. Well, it was a big day for both sisters as they could celebrate together. Alix had on a really awesome red two-piece outfit that probably turned a few heads. 

Alix wrote, in part, on her Instagram post: "So excited for this next chapter of your life & to continue watching you blossom into this amazing woman (who is somehow cooler than everyone without trying). Forever grateful that I get to call my sister my best friend :) love you".

Now, will Ashtin start sharing even more photos from her life? Time will tell. She might take a few tips from Alix, who has millions of followers on her social media platforms. Keep your eyes glued, too, as Alix probably will put up pictures during her summertime fun.
