Dip-Dye to Die For

You guys, this is soooo me:

Anthropologie "Half-past-six" trenchcoat by Taikonhu, $198. I tried it on at the store last night and it felt so lovely. Unfortunately, that price tag is sooooo not me.

I'm seriously considering a DIY fix. I'm thinking a box of dye and this Target trench might do the trick:

Isaac Mizrahi for Target wrap trenchcoat, $44.95.

Whaddayathink?
