Pajama pants - nice soft & loose. I have a pair of men's pajama pants and not sure why but they always seem so much softer than the women's that I find? Anyway, if they have a drawstring they should work for you as long as they aren't too long. Baggy shorts are the other pants that I lived in the first few weeks. I didn't wear my regular athletic shoes at first since I couldn't lean over or bend the right way to get them on & tie them. The slip on sneaks that I bought worked in a pinch, but I mostly wore skid-socks in the hospital and at home.
I remember day three in the hospital which was first day of group PT (missed day 2 since I passed out in the hall on the way there and had to have a transfusion). I feel as though I've gone a few rounds with Mike Tyson and don't look much better. I drag myself into the PT room in baggy everything with hair scrunched into a ponytail, expecting everyone else to be about the same. The first woman already there is in a nice shorts outfit with athletic shoes and has full makeup, freshly styled hair, jewelry and accessories! What? We had surgery within hours of each other?? Of course, she asks me how I'm feeling as I'm now known as "the one who passed out". Great.
Good luck - you're on your way to feeling SO much better!
