Indie rock star Florence Welch, the lead singer of Florence + The Machine, told "Nightline" she "always" decorates the walls of hotel rooms with kimonos to make them feel more cozy.

"It's just wanting to sort of feel at home," the British native said. "Otherwise I feel a bit mad. … That's partly why I buy a lot of kimonos because they look so good on the walls."

But she does actually wear them as clothes too. Having dozens of kimonos at the ready is also quite the convenience.

"They're good, you know, because I wear them out quite a lot," Welch said. "I think you could wear them as sort of dresses."

Welch, 25, talked with "Nightline" anchor Cynthia McFadden about growing up in South London, starting her career wearing "boyish" clothes and vintage outfits found at thrift stores and still has "pinch yourself" moments. This once tomboyish singer has now become a darling in the fashion world. In October, Welch performed and walked the runway for Chanel's spring/summer collection during Paris fashion week.

"It wasn't really the singing that was the problem, it was the walking," she said, laughing. "I didn't know how to do it. … There were three moments at the end of the walk where I didn't know what to do."

Florence + The Machine quickly rose to fame, first in the U.K., after the release of their smash hit single "Dog Days Are Over" in 2008. They broke through to the American mainstream pop charts after the song was featured on several popular TV shows, including "Grey's Anatomy" and "Gossip Girl."
