I got a g-string hot wax at Simply Beauty and am very happy with the results. It did not hurt at all and looks spotless. The beauticians are lovely too.
I booked here 2 hrs in advance because everywhere else needs an entire days notice. I received a call an hour later saying they need to reschedule for 2 hours later. My advice is to call whatever venue up if you make a short notice appointment because not every checks their booking system constantly.
The chest and stomach wax took 20 minutes. It was quick, possibly a little rushed but I have nothing to compare it too.
