No sweatpants, grungy t-shirts or frowns for this newly-single lady! Taylor Swift stepped out in Pacific Palisades, Calif. on Tuesday Jan. 8, and for her very first sighting since her ugly split from Harry Styles, the 23-year-old star took pains to look stylish and composed. Visiting a private home, the "I Knew You Were Trouble" singer wore a striped, long-sleeve mini-dress that accentuated her slim figure plus knee-socks and flats.

Her best accessory? Red lipstick and a faint smile. Her ex Styles, meanwhile, was seen in London hours earlier heading into a music studio with his One Direction bandmates.

By all accounts, Swift and the British crooner, 18, did not bid adieu on good terms. During a vacation on Virgin Gorda in the British Virgin Islands, the couple of a few months "had a fight," one insider explained. "[Harry] said something he shouldn't have . . . This [breakup] is definitely going to be for good."
