scheduled csection questions..

je

So here are my questions for anyone who has had a c-section before:

-Do I have to take off my nail polish before the surgery? Can I wear makeup? Are piercing rigs allowed? I have my nose& a few earrings (all hard to take off)

-Do they give you underwear to wear at the hospital...I just feel like any I buy are not comfortable enough..

-Is it best to not take pjs and just be in a gown the whole time?
