Hospital Attire

Hey, gals! I'm a FTM, so I'm trying to wrap my mind around what all I need to wear at the hospital. I've been told that pajamas that button down the front are good because I plan on breastfeeding. However, I've read a lot of people saying they just wore nursing tanks. So, I want to hear what all you mommies out there sported after birth and for visitors that is also easy access for baby to breastfeed!
