Mocha Colored Dress from TOhRCH SELECT

I've never heard of this brand before, it's my first time coming across it. I also don't know what this is.. it's not really a dress, but it's not really a shirt either. They call it a gown, but I don't really consider it a gown either.

I love the little ribbon on it, and the flower detailing at the waist. Whatever this is, I think it's cute.
