Look, everyone! Les Mis has a clothing line! Now we can all look like street urchins.
Seriously, I'm pretty sure Cosette is wearing this exact...thing....in the familiar Emile Bayard picture.
Either that, or it's the Providence Top at Anthropologie for $58. The product description says that the "frayed and asymmetrical trim" give the piece a "natural, handmade feel." I'm guessing it's sort of what it feels like to sew random pieces of ratty crap together in an fugly non-color and call it a "top."
And no, it's not any better in another color.
