I love it too, I want the signature wristlet so bad! It reminds me of the color "mist" from years ago.
You are so right, but it is a brighter blue. I got the medium wallet but also have the soho wallet in mist. I just looked at them side by side last night and the turquoise is definitely brighter.
OP - i say go for it! I opted for the black hobo and got the wallet for a pop of color!
