Try to wear something that is not restricting at all and also that you won't mind throwing out if you need to (Sometimes they get stained). I started out in a lite t-shirt and DH's trackie pants but I got in the shower so I nuded it up and stayed that way until after my shower after having DD. I was surprised at that because I'm the biggest prude and I always said I wouldn't have DD nude. Make sure you pack extras of what you decide incase you need to change due to staining.
