Before I found KB I would have told you that muus were for my grandmother. And maybe they are, but these are so dang versatile (and gorgeous!!!) that they’re for me and everyone else.
In this picture I have it tied up on the sides to make a blouse kind of thing, but they can be worn loose, tucked, layered under, layered over, and so on. These are not my grandmother’s muus! (Though she was a cool lady, so she would have loved these too!)
