OUCH!!!
I have them periodically. You leave your panties on, usually they will drape you with a cloth. They will ask how "high" you want to go. THey they will have you hold your panty back. They put down the hot wax, place a disposable cloth-like thing over it, press down firmly, and pull it away. Kind of like pulling a band aid off-only 1000 times more painful. They then will tweeze the stragglers. There is a bit of a technique to it. Sometimes they will do a small bit at time, other times more. You can go shopping afterwards. I wax my eyebrows also-that is painless compared to a bikini wax. The good part about a bikini wax is that it takes a littlebit longer to grow back, which is nice if you are going on vacation and going to be in your bathing suit a lot.
