We're not sure how she squeezed it all in, between her crazy "Blank Space" performance  and attending that 1975 concert , but Taylor Swift  has managed to be the world's best BFF yet again. On Saturday night, she helped Modern Family star Sarah Hyland celebrate her 24th birthday, partying it up with other notable names like Jaime King, Hailee Steinfeld, and Lorde.
Our Instagram feeds were flooded with festive photos from the night, leaving us wondering (yet again!): what's a girl gotta do to become part of Taylor's crew? Well, judging from who she chooses to chill with, we're thinking the singer has a thing for stylish friends. Ahead, we rounded up the most fashionable ladies  who are in Ms. 1989's inner circle, proving that a good pal is truly a girl's best accessory.
