Full disclosure: I have the flattest chest known to mankind, so plunging necklines and whatnot don't usually do the trick when I want to show a little skin. I love the effect of these casually cut-out shoulders — they're subtle and sensual, the skin-revealing equivalent of locking eyes and sharing a small smile from across the room (as opposed to grinding up on a dude and assaulting him in a beer-fueled haze). Maybe I'll sacrifice an old tee for the cause. It seems like it requires a cool factor much greater than anything I could muster, though... what are your thoughts?[photo cred to Chiara Ferragni via Musings in Femininity]
