I've done a bit a of investigative work. $149 buys you this comfy, versatile piece. Kind of expensive but I foresee myself getting a lot of use of it. Strolling around Paris, wearing my large rose colour Coach sunglasses, hopelessly engulfed in the scenery.
The designer is Canadian Stacey Bafi-Yeboa, who was inspired by the crime of wearing overly casual clothing in public (ie pjs). Her pieces are made from cotton, bamboo and lycra. Bafi-Yeboa sought to find the middle ground between sloppy/comfortable and chic/uncomfortable. Personally, I'm usually willing to make the sacrifice without complaints but this is a promising alternative.
