I bought matching long and short sleeved gown and robe, all in purple. They look nice on.  My husband can't stop admiring me in them.  He says I look like a princess (In size 2x yet).  They are opaque. So I can answer the door and walk about.

I always thought that cotton or flannel would be the most comfortable and that synthetic would cling or be sweaty.  But the reviews were good so I took the chance.

How wrong I was! They are comfortable and smooth as silk.  They don't ride up or bunch up.  I machine washed and dried them and they came out fine.
