This is from the H&M Fashion against AIDS collection from 2 years ago. I love that it is actually a unisex piece that can be adjusted just as you wish. The collar can be zipped off, the sleeves let down, with or without the belt. I adore the versatility.
People say it looks like a bathrobe, but they don't know what they're talking about.
Funniest comment I had on this one over the years: "So, is this like a jesus robe or something?"
