Robe for the hospital?

I bought myself a robe with a sort of nursing nightgown today. I thought I really wanted it but now I am wondering if I will even use it at the hospital. Did anyone wear one with their first baby? I didn't have one with my first baby but I did want one at the time. I am just asking because it was quite expensive and I would like to return it if it's one of the useless things.

Its not the one in this picture but very similar.
