Taylor Swift says you have to "dress the part" when you leave the gym.
The 'I Knew You Were Trouble' hitmaker has responded to critics who comment on her glamorous image after a tough workout, and joked it's how "everyone looks" following a training session.
Speaking to 'Late Night' host Seth Meyers, she said: "That's how everyone looks when they come out of the gym. "I like to bring a change of clothes, OK. I just like a change of clothes. I bring a hairbrush with me."
The 24-year-old singer also insisted she feels like she needs to "try a little harder" when she's walking in New York.
She added: "New York feels like one of those cities worth dressing up for. "I just feel like when i walk out on to the sidewalk in New York I have to just try a little harder. "Everybody looks like that at the gym, coming to and fro from the gym. You have to really dress the part."
Meanwhile, she has also discussed her dance moves at award shows, and explained she throws shapes because of nerves.
She has said: "I used to get really nervous at awards shows because, seemingly, they're a huge pressure cooker. And everybody seems to be sitting there trying to look more unaffected by being at this awards show than the next person next to them.
"That can have an effect on you, and so you're in the front row and you're sitting there like, 'Maybe I should sit here like this.'
"A couple years ago I just decided, 'No. This is the coolest concert you could ever go to.' "
