Jennifer Lawrence
We love that the The Hunger Games star doesn't have to work out in some matchy-matchy spandex suit. Her Led Zepplin T-shirt and black running pants are probably the first things she grabbed out of the drawer.
Fergie
Ripped jeans, baggy tanks, and her husband's flannel tied at the waist is quintessential Fergie fashion. She always maintains the rocker-chic vibe even though she isn't dressing to impress.
Amber Rose
Let's not forget that Amber Rose is the celeb who recently wore a metal G-string "dress" on the VMAs red carpet. Here she's dressed like a '90s lumberjack who is about to do some jazzercising in her sneaks.
Ashlee Simpson and Evan Ross
At least these newlyweds are united in their "don't care" style of dress. Alhough we have a feeling that Mr. and Mrs. Evan Ross put a lot of thought into each ensemble—even if it ends up looking like they both grabbed clothes from an old pirate's chest.
