You do get hassle in the markets to a cartain extent, however if you go prepared with this in mind then you should be fine. All the shopkeepers are proud of their stock and want to show you everything! It's their living so they are very good at it. My wife wanted handbags and purses this year. Obviously they are all fakes out there, so you have to bear in mind what you want to pay for a fake leather handbag. Essentially what you are paying for is just a leather handbag/purse with a Gucci/Prada label on it. We went on the premis of what you would pay for a good quality leather handhag in the UK, so we were averaging about £10-£15 per item. We always checked the stitching first.
Don't enter into a bartering situation unless you want the item, it's considered bad form. Looking is fine, just smile and say 'no thankyou' nobody was offended when we did this. There are some great bargins to be had at Icmeler market.

As for male hassle, we didn't hear much of it. I suggest your daughter keeps her sunglasses on as much as possible and avoids direct eye contact if she's shy or at all worried. The men are all very charming they even tried to charm my wife! It's all light hearted and part of the Turkish way. I have to say the English girls at the Palm Gardens were taken with one of the barmen. He was obviously the holiday hearthrob for 2006!
