For her live performance of "Blank Space", Taylor Swift wore a black blazer courtesy of KaufmanFranco's fall 2014 collection along with black Christian Louboutin ankle booties, fishnet stockings, black satin shorts, and jewels courtesy of Lorraine Schwartz.
On February 25, 2015, the day of the Brit Awards, Taylor Swift surprised a fan named Sinead Murray, who camped out the freezing cold for 20 hours just to catch a glimpse of her as she stopped by BBC Radio 1. Murray later told Buzzfeed that Swift followed her on Tumblr a few months prior. So Murray herself, had been uploading pictures to show her there were lots of people there and that they were excited to see her.
When speaking to BBC Radio 1, Taylor Swift revealed that rehearsals had not gone to plan. She said "It's weird I'm your last guest because I am actually opening the show. I am changing into a performance outfit then back into this to watch the show. Rehearsals didn't go well at all, they accidentally started the music before I was on stage, so I was running out shouting 'I can show you." Tyce Diorio would serve as the choreographer for Swift's performance with many of the dancers being employed by Monsterz Crew and Fiya House.
