Have a read of the Boobie Bible, it’s got some awesome tips on there!
One which I won’t forget is apparently pulling up your pants is painful! If you cross your arms over and pull your pants up it doesn’t hurt (if you know what I mean!).
Also I read that someone had a onsie but they regretted wearing it, as you can’t use your arms very well after surgery so once it’s around your ankles it’s hard to pull them back up, so suggested a nightie.
Good luck – keep us posted! xx
