There's nothing more magical than a sisterly bond.
The duo sported Marc Jacobs fall runway white prairie dresses with bell sleeves featuring a pattern of small blue flowers, along with dazzling dark grey-feathered and bejeweled capes.
The sisters were absolutely glamorous and sophisticated and their outfits likely would have made Princesses Anna and Elsa proud.
Gomez, 27, wore her hair in two perfectly messy braids while little sister Gracie wore her hair back, with her bangs on display.
The sisters have always been close, despite the 21 year age difference.
In 2017, Gomez posted a sweet home video, with a promise to her little sister on Instagram, writing an inspirational message directed towards Gracie.
"I will forever let my sister know she is strong, bold and beautiful. She will be raised to know her voice matters. She is going to understand the importance behind being a leader and inspire others by her truth," the "Look At Her Now" singer wrote.
Gomez’s mother, Mandy Teefey, welcomed daughter Gracie Elliot with husband Brian Teefey in June 2013.
