'Tis the season for holiday hosting!

Last Friday night Ariana Rockefeller decked the halls with an intimate group of friends at her new Upper East Side apartment.

Ever the stylish society staple, the model slash philanthropist slash equestrian wore a beautiful lilac dress from designer Christy Rilling. 

And her home? 

Well let's just say the posh pad is the very picture of sophistication.

Not your average uptown affair, guests including Mei Kwok, Lilah Ramzi, Zach Weiss, MaryKate Boylan and more were treated to a tasting of Chrome Horse Tequila, a new spirit brand created by Ariana's friend, Jack Morgan.

Following the holiday cocktail soirée, Ariana changed into a custom pale pink gown handcrafted by Greek designer Vasilis Zoulias and headed up to The Bronx along with her fashionable flock for the New York Botanical Garden's Winter Wonderland Ball.

“It is a wonderful feeling to be able to host friends again, especially around the holidays and now in my new NYC apartment. The New York Botanical Garden is a beloved institution for all, as it certainly was for my Grandparents, and supporting their renowned Children’s Education Program is a cause dear to my heart.”

Curious to see inside the socialite's holiday housewarming?
