Papier Women's Heather Hooded Velvet Robe with Elastic

When I received this robe, I saw that it was very good quality (soft, hooded, and well made). HOWEVER, I'm not sure the sash is a good idea the way it is made. When I washed the robe it on gentle cycle after removing it from package, the sash had wormed its way inside the hole. Therefore, I had to completely pull the sash out of from the other side and fish it back through the hole with a Sharpie pen to guide it. Absolute pain!!! I guess the best option would be to keep the sash tied well (or even knotted) before you wash to insure that the sash won't move. I guess I should have known better.
