Okay, so if you want to get the ‘feel’ of Key’s Sherlock-era style, both on and off stage, a good choice would be vintage-y denim, studs, and Americana.

That being said, Key’s denim vest/shirt from I AM is by DSquared. And the star-print shorts are by Joyrich.

However, here are 2 vests from By The R that have the feel you’re looking for.

Mo' fashion.
The vest is cute. I might would get it.

Wait.. Would Key come with my purchase? ;3
