Kim Kardashian certainly knows how to make an entrance!

The SKIMS founder, 41, made a bold fashion statement as she attended the Revolve event in Los Angeles on Thursday – her first public event since being declared legally single amid her ongoing divorce battle with ex Kanye West earlier this week.

"Kim got to the Revolve Social Club before it was open. She was in great spirits," a source tells PEOPLE. "Someone commented on her outfits and she replied, 'I remember every outfit I've ever worn.' "

"She had a 'Berry-Mint-Kenny' drink and told the bartender she likes sweeter drinks," the insider revealed. "She was bragging about her sister's company."

During a bifurcation hearing on Tuesday, a judge granted the Keeping Up with the Kardashian star's request to be ruled legally single – a decision she was "relieved" to hear, a source told PEOPLE.

"Kim has considered herself single for a while," the source explained. "She is relieved that it's official though. She isn't looking back and wants everything about the divorce to be final."

"She is in a very happy place right now," the source added. "It's taken her months to get to this point. She feels good about life."

The reality star filed for divorce from West in February last year after nearly seven years of marriage.

In October, the KKW beauty mogul and Saturday Night Live star Pete Davidson sparked romance rumors after they were photographed holding hands on a roller coaster ride at an amusement park in Southern California weeks after Kardashian hosted the long-running sketch comedy show – in which she and Davidson, 28, shared a smooch during a skit.

A source told PEOPLE in February that "friends are excited to see her genuinely happy" amid her relationship with Davidson.

"Everyone around her is just happy she's happy," the source explained.
