Not trying to be mean, but honestly it looks like an old lady, or at the very least like a cast-off, hermit type. The way you have it in your profile picture has a younger look to it. Anything beyond that is too much scarf in the hair.
i'm not gonna sugar coat this...put that away...and don't speak of it ever again,if someone mentions it...it NEVER happened,NEVER.you know who wears that in my country?old ladies that work on farms and they wear it not cause it looks good,cause they need it to keep the hair out of their face.
I've NEVER seen someone wear a scarf on their head like that, or claim its "retro"..made me giggle a bit. In my opinion it does look a little oldlady like. If you like it wear it, maybe it'll catch on ? better to be unique then plain and boring, anyday.
