Some celebrities are invested in Fashion Week because of the clothing, while others have a more personal reason.
For Cindy Crawford and Camille Grammer, part of the fun was watching their daughters model the latest fashions.
Kaia Gerber, Crawford's youngest child with husband Rande Gerber, and Mason Grammer, Camille's daughter with ex-husband Kelsey Grammer, have both walked in shows for Spring 2018 New York Fashion Week.
Gerber, 16, appeared in Raf Simon's Calvin Klein show Thursday, while Grammer, 15, walked for the Malan Breton Collection the same day.
"CALVIN KLEIN! there are no words to describe how I feel, I love you endlessly Raf!" Gerber wrote on Instagram after.
"Felt like a princess for a day," Grammer wrote of her experience.
Though models like Kendall Jenner and Gigi Hadid are ubiquitous these days, few may know that Mathilda Gianopoulos, Molly Ringwald's daughter, appeared in New York Fashion week this past February, as did Delilah Hamilton, Lisa Rinna's and Harry Hamlin's eldest child. Meanwhile, Shaquille O'Neal's son Myles appeared in the Dolce & Gabbana show during Men's Fashion Week in Milan this past June.
