If, for you, Christmas is strictly about tradition – red ribbons, glass baubles, hand-me-down angels – look away now. Because, in some quarters at least, the Christmas tree has become a canvas for cultural devotion, with entire fandoms taking up residence amidst the fairy lights. Still basking in the shimmering tidal wave that was Taylor Swift’s Eras Tour one year on? Obsessively picking over Lily Allen’s shatteringly good West End Girl? Well, now’s the time to show your love for these icons via your tree as this festive season turns decidedly pop-cultural. Sure, they’re not for everyone, but if you consider yourself here for any of these year’s defining cultural moments, then voila: these are the fandoms that could be shaping your seasonal spruce this Christmas.
