Gigi Hadid had a denim-themed birthday party and the looks were amazing

We love a good theme and Gigi Hadid nailed it.

Gigi Hadid celebrated her 24th birthday with a star-studded denim-themed party and it was a very cool sight to see.

The famed model was spotted on April 22 in New York City stylishly wearing a denim jacket, jeans, white crop top and black boots.

Her sister, Bella, was also on the scene wearing a fun look that included a micro-sized Louis Vuitton shoulder bag, an opened button-up denim top and a matching bustier underneath, along with hoop earrings.

Bella posted a fun video clip on Instagram flaunting her look.

Other notables at Hadid's denim-inspired affair included Ashley Graham, Olivia Culpo, and the sisters' mother, Yolanda Hadid.

From the looks of it, this was one of Hadid's best birthdays ever, and she did it in high style with nods to 1990s flair. Keep scrolling for more delightful denim moments from the evening.
