C-Section Prep: What Should Be In my Hospital Bag?

Amanda
Had our 36+3 check up yesterday, and baby is still breech. Doctor is scheduling a c-section, but also confirmed that my body is naturally progressing with labor, almost dialated 3cm and 60% thinned out. I had a vaginal birth with my first, and it was super easy. 
Any mommas out there have some feedback on what helped with their c-section, what they wouldn't have made it without, what they should have packed? 
I have a general list: 
Two nightgowns / robe 
My own pillow 
Calf length Tshirt dress to go home in
Granny panties
What else?
