I love the cashmere holiday collection this year from Restoration Hardware. Here are a few of the pieces I am adoring and I also think would make wonderful gifts for the person on your list that seems to have everything.
I love these cashmere hand warmers and for $15 you can't beat that!
cozy robe for your lazy Sunday mornings
cozy cashmere blanket for cuddling on the sofa while you watch your favorite holiday movie
cozy touch of comfort for your living room sofa
All that a person would need now is a good cup of hot chocolate, a book, and some cookies straight out of the oven!
