I bought pajamas from Walmart. The kind that button up. Then I just went straight to bed.
But yes, best to have them buttoned or zipped. You will be wearing a hospital gown so this makes things easier. Your clothes will be just for going back home.
Bought extra large sweat pants, t shirt, and zip down hoody. Last thing I wanted to worry about was not being able to get into my clothes because I was uncomfortable and I was right. I was crazy swollen too!
I wore leggings and a button up shirt.
Wishing you well!
Sweatshirt and sweatpants.
