Going in for TT tomorrow, need a little advice

Going in for my TT tomorrow (with muscle tightening). I'm wondering what to wear while in the hospital. My usual go-to is basically loose fitting pants with a draw string waist and a t-shirt, because I hate feeling like I'm walking around in pajamas. Am I going to be able to tolerate pants? Or do I need to go ahead and bring a more nightgown like option?  

I wore yoga pants with no problem.

Happy healing!!

I had to many drains that were pinned too low for me to wear yoga pants.  I had to wear a very long, loose tunic and wear my pants super-low underneath where my drains were pinned.  

I just had a panni and a tummy tuck. I came home in very loose sweatpants and a loose shirt. I leave the drains outside of the pants and covered by the loose shirt. Nothing tight, your surgeon will get pissy about anything that it too tight against the incisions.
