Here's is the online description for the PM. I do think it would look great over the shoulder!
"Inspired by the adventurer spirit of the FW16 show,the Atlantis bag is the star of the season. The ultra-supple Monogram canvas and sleek design make it spectacularly modern and functional. It boasts a turn-lock closure, an exterior zipped pocket and an interior flat pocket for direct access to your essentials. Thanks to its handle-fastener and signature large removable strap, it can be carried by hand, over the shoulder, or cross body."
