The label states that this long emerald kimono-style robe is hand made by Nippon Nobility in Tokyo. I asked a seller on another site about it, as she had a similar item, and she said that as far as she knows it is silk and vintage. I am not making those claims in the listing, as I do not have verification, but it is beautiful! Around at the underarms, before tying, it measures 52" so will fit just about everyone.
As much as I prefer to hand-wash than dry-clean, I would strongly recommend that this be dry-cleaned.
Buy more than one item from my shop and I will refund excess shipping via Paypal.
