Dressing up for New Year's Eve can be a right pain in the bum. Do you go with sparkles or play it safe in black? Do you wear thermal knickers or brave the arctic elements with bare legs?
Both gals went for bold red and black outfits so naturally we only felt it was right to have a bit of a compare to see who wore it best...
First up was Taylor and with a certain Harry Styles shaped admirer waiting backstage, she clearly had some impressing to do.
Bearing in mind it was absolutely freezing, she went for the sensible option and paired a slinky pair of leather trousers with boots. Let's hope she didn't get too sweaty up there on stage or we'd imagine there might have been a Ross from Friends sort of moment when she popped into a portaloo for a wee.
There were no frills with this outfit and she topped it off with a touch of sparkle on her biker jacket, which was naturally in her signature colour of red.
Next up was Carly Rae who added a slightly more dressed up approach to proceedings.
Despite the fact that it was freezing, she manned up in a black crop top and full length red chiffon skirt that we can't help thinking has a touch of the 80s to it.
Sweeping about on stage, we are loving the look, which she also let speak for itself, just leaving her hair long, loose and wavy.
But whose look do you like best?
