My hubby loves toasty bathrobes. He wore his old one to death some years ago and we never replaced it because he could never find a bathrobe that had all of his "requirements":
Hood.
Long sleeves.
Deep pockets.
Tie not attached.
Super long length.
The bathrobes we found were usually lacking in the super-long-length department as they mostly came only to just below the knees.
So, I bought a pattern and altered it to make it super long...and I made him a robe out of fleece with a hood, and long sleeves, and deep pockets, and a non-attached tie AND a length that came down to his ankles!
He loved it and had no clue that I had been making it for him. I find him wrapped up in it on the couch...with only his nose peeking out of the hood and his slippered toes barely peeking out of the hem.
