Slimming Corset

My friend sms that she has wore a slimming corset for four years and she is staying slim. It is almost like the slimming dress. I am shocked to find out how much she bought it. She told me she pay using installment. Can you guess the price of the slimming corset?

I think nobody can guess it right, it is $1,500. She wore it for four years and maintains her body shape. She also told me that she has been to gym before and it cost her $170 every month and she has stopped as not going any more.
