Twilightcore , or Twilight Autumn , is an aesthetic that rose to prominence in Autumn 2021 on TikTok. The trend is primarily focused on the fashion of the late 2000s, specifically emulating Bella Swan from the Twilight franchise and Elena Gilbert from The Vampire Diaries . Despite the fact this aesthetic is mostly associated with these characters from pop culture, it can also be seen in the style and actions of Violet Harmon in American Horror Story: Murder House and also Tracy in Thirteen .

During the COVID-19 pandemic of Autumn 2021, the app TikTok experienced a Twilight renaissance. It might seem unusual at first glance, but nostalgia is quite strong in this generation. Combined with pop culture's "20 year rule", people revived the late 2000s.

Nostalgia is only one of the factors that ushered in Twilightcore. With 2000s fashion making a return, Netflix introducing the Twilight franchise to their platform at the time, the weather progressing into winter, and the aforementioned nostalgia coincided perfectly and created what we now know as Twilightcore.

Twilightcore has muted colors and dark hues. The aesthetic is meant to have romanticized overcast scenes and desaturated clothing. This aesthetic is usually based in suburban neighborhoods and schools or deep in forests. The fashion for Twilightcore is based on the Twilight series and the Vampire Diaries series.
