Taylor Swift [2] has spoken: the bob haircut [3] is here to stay. The musician declared it so on 11 Oct. at the premiere of her concert film "Taylor Swift: The Eras Tour." The event was attended by quite a few industry heavy hitters (hello, Beyoncé), but all eyes were on Swift as she shined in a baby-blue Oscar de la Renta gown and the trendiest hairstyle of the moment.

While it's unclear if the pop star fully committed to the haircut [4] or just went for a tucked variation of an A-line bob [5], fans have been in a frenzy nonetheless. Searches for Swift's haircut dominated the internet overnight with many people wondering: did she cut her hair for real or is it just for show? Either way, it feels like Swift is trying to make a statement. Getting a dramatic haircut is one of the main ways people signify they're entering a new era, be it after a breakup [6], starting a new job, or making a big move. And this is not just any haircut. Bobs are typically the style of choice for powerful women in TV and film [7], an archetype that the singer fits to the letter. Either way, now that Swift has officially provided her stamp of approval, it's official: bobs simply are the moment.

This isn't the first time a Swift hair change has caused a stir. In fact, just a few weeks ago, fans were convinced that her fringe from 2014 [8] were a clue to her vault song puzzle [9] on her forthcoming "1989 (Taylor's Version)" [10] album.

Though she is one to typically stick to a signature look that works for her, Swift's new style comes at a time when bobs are heavily trending — and that's putting it lightly. Everyone from Lori Harvey [11] to Hailey Bieber [12] has been spotted in their own version of the short hairstyle [13]. This trend is really versatile, so regardless of your hair type [14] or texture, you can achieve the bob of your dreams. Swift still has quite a few shows left on her tour, so it's yet to be determined if she has another big hair moment up her sleeve. In the meantime, take a closer look at her bob haircut below.
