Retail $80, now $33.95
This tunic from BB Dakota is a fun take on the classic white shirt. It's a versatile piece, could be worn as is or cinched at the waist with a thin belt. It would look great with skinny jeans, and because it's long enough, leggings would work too.
It's currently $80 at every site on the web (Shopbop, Revolve, Amazon, etc) except for Karmaloop, where it's on sale for just $33.95. It's also available other colors like taupe and blue.
