The what of what makes an "It" girl an "It" girl is hard to pinpoint. Is it their ability to master fashion trends? Their nepo-baby status (well, we know that certainly doesn't hurt.) The most legitimate answer, in my opinion, is individuality. When everyone follows the same sartorial theme, someone with a bonafide "It" factor will wear whatever they want, like a very chic black sheep. Someone who marches to their own fashion drum—that's where the "It"-ness comes into play that sets them apart from the rest. Zoë Kravitz's outfit for Taylor Swift's birthday party is a quintessential example of personal style prevailing above all else. While all other attendees opted for their best bejeweled dresses and "Reputation"-era leathers, Kravitz wore a crewneck sweater and simple navy trousers.
For those who somehow missed National Taylor Swift Day, yesterday was the pop star and business mogul's 34th birthday—and it was an epic, spare-no-expense blowout (boyfriend Travis Kelce said "money [was] no object" when planning Swift's birthday party). The woman of the hour wore a beaded and bedazzled mini-dress by Clio Peppiatt that featured a galactic print of moons and stars. Swift's blonde bestie, Blake Lively, wore a grunge leather midi dress with a thigh-level slit and statement, punk rock-esque Christian Louboutin stiletto boots.
