Arabella Kushner definitely looks grown-up in the birthday post by her mom Ivanka Trump, particularly in the photos from her bat mitzvah, held in the weeks before her birthday. For the coming-of-age celebration, Arabella wore a blue and gold metallic layered dress by Custom by Zoe. "We began working on the concepts for her bat mitzvah in January 2023," a spokesperson from the brand revealed to WWD. "We are honored to bring the vision alive. Arabella looks absolutely magnificent." And what's even cooler about the dress is that the bottom layer looks to be removable — in the family photo with her aunts and uncles (no photo with her grandfather Donald Trump), Arabella's wearing the shorter version of the custom dress along with some sparkly Nike sneakers.

Ivanka posted pics from Arabella's bat mitzvah a month or so before Arabella's birthday with more messages of love and support for her daughter: "We couldn't be prouder of the extraordinary young woman she has become. Her kindness, creativity, humor, empathy and passion have filled our lives with so much joy and inspiration."
