This might not be the standard reason for purchasing a robe, but it was a big hit!
So, I purchased this robe as a gift for a friend who had a procedure and needed some take-home medical equipment to remain attached to him for a week.  I thought this would give him a comfortable way to stay comfy and warm without having to get properly dressed.  It worked out great.  He was super comfy and it gave him an option to hide the equiptment from visitors.
I did initially think they sent the wrong color and then I looked back and nope.  *I ordered* the wrong color... He didn't seem to mind that it was pink though. :)
