Halter hoodie

Very unique halter hoodie. I bought this in a lil boutique in San Diego awhile back and have never seen another like it. It's a very pale blue color. It is a super soft terry material inside and smooth cotton outside with a silk lining in hood. This fell just beneath my belly button. There is no size tag at all but based on the sizes I wore when I bought this I'm guessing a XS to S.
