If you will be in Patong, there is one that comes highly recommended. It is "Mr. Singh Fashion Gallery" and it is at 2 Ratuthit Road, Patong.
Ive just come back, and I didnt get any clothes made up, but as I said, this guy was highly recommended.

I agree with you that $85 for a suit, shirt and tie is gr8 value. Years ago suits used to cost hundreds. Now ... they are much cheaper here and you can get one for b/n $50-$100, but not really good quality and you then usually have to pay to get pants hemmed and jacket not really good fitting. At least with tailor made suits, they are exactly that - made to fit your body!
