Ladies help! 1st brazilian wax? - should you shower before you wax

please, if you could answer these questions, advise I'd really appreciate it! =]

1. What kind of clothes should I wear?
2. I make my shower? (Yes and no, I have heard what) is your opinion
3. What is "normal." . . Fight, redness, itching normal and how long will it last? They appear the next day or immediately?
4. How extreme should I donate? I think my wax costs about $ 60.


Any advice would be very grateful! =)
