On Sunday, Dita Von Teese threw her annual "Garden & Arts" bash at the Kia Motors Malibu Estate, where her closest friends dressed up in costumes ranging from dinosaurs to cats to flowers.
Wearing an elegant green gown with a pop of red from her peek-a-boo bra and Louboutin flats, the hostess was "in great spirits" as she hung out with her pals during the day party.
Von Teese, who recently launched a new lingerie line with Destination Maternity, had an array of unique activities at the party, including a candle-making station, a mask-making station and a paper flower origami station.
Guests also got to make a wish during a "wish-a-saurus" ceremony, where they placed wishes inside of a dinosaur-shaped piñata and read them aloud once it was destroyed.
"It was amazing and artistic," a partygoer tells PEOPLE. "Dita was in great spirits."
