I love this look and as soon as it gets just a little cooler I can think about wearing it. Right now it's warmer than usual about which I am NOT going to complain - stretching out the summer a bit is never a problem in my book.
My interpretation would be more classic, with slim pants, a boatneck sweater, and either a hobo or a cross body bag, both of which I have in very simple designs in soft leather.. Of course I have THREE pairs of black loafers to choose from! (Looking for a dressier black flat shoe but no luck yet). I also have a floral sweater that I'd like with this look.
Might try a darker nail polish too - I've been polishing my nails a bit lately and love the burgundy idea.
