I haven't seen anybody in real life wearing the bathroom coat, but I have seen multiple bloggers wearing it and I've seen the bathroom coat at several webshops. I honestly don't really get, because I would really feel like wearing a bathroom coat. But for the people who are braver than I am, I found a classy one at New Look.
It's certainly more on the pricey side, it's € 99,99. You can see the coat here. What do you think of the bathroom coat?
