You've been dutifully liking pictures of whatever your friends,"musical eroticism" eubanks winkler#tbm=bks co-workers, casual acquaintances and family members did for Halloween, but now it's time to focus on what matters -- Taylor Swift and her celebrity friends.

T.S. owed much of her Instagram feed last night to Ryan Reynolds, who hooked her up with an actual Deadpoolcostume from the movie, because Taylor Swift does not simply walk into Wal-Mart.

Squad ghouls!

Reynolds, a Taymerican Fourth of July attendee, is the husband of squad member Blake Lively, who gave her stamp of approval.

Swift was joined by a few core members of the Sisterhood of the Traveling Crop Tops for what appears to be a cozy night in at Swift's home.

The elite guest list included Gigi Hadid as a Cub Scout, Martha Hunt as Marcia Brady, Lily Donaldson as a space cadet, Emmie Gundler as a black swan, Kennedy Rayee as a cat and Fifth Harmony's Camila Cabello as a cat lady.

Cabello, who may or may not be Future Taylor Swift, holds sign claiming that, "Meredith is missing." Indeed, Olivia Benson was spotted at the shin dig, but where's Meredith Grey?

At the end of the night, they drank wine in a bathtub, which seems kind of uncomfortable, but OK!
