Where and how much are the belly dancing costumes in the area? 

We have asked about the prices for the Belly dance bra and belts in several shops in old part of Marmaris, near the bar street. The belts prices start from 25 Turkish lira, which is about 10 GBP, and the bras prices start from 35 million Turkish lira, which is about 15 GBP. You should of course bargain the price, as it is sold in the bazar with no price tags – a perfect place for a good bargain.
