Hi Gina,
Last year I had a couple of skirt & pant suits tailored at Narry's and I was very happy with their service and the finished products. They were not pushy. You will see their signs everywhere!
Just a hint & FYI - You will most probably be given brochures at the airport, hotel & in the street showing deals from tailors, where they claim to make up a certain number of items for say, USD300-00. From experience, this is usually the cheapest fabric, just to get you into their shop. Then they'll show you what they can make you in a better fabric, for a dearer price.
In 2001 I had some clothes tailored at "John's Tailors", which were also excellent.
Regards,
Shaz
