What are you going to wear to give birth?

Seems like a silly question I know...but as I keep getting the emails about it getting close to bag packing time, I told my husband this and he said, "what are you going to wear?" I hadn't even thought of that! With my daughter, I just wore a big t-shirt but didn't go to the hospital planning to birth in it. Now I know I can have options so...hmm...what to wear, what to wear??
