We tried to find reviews on tailor made suits and didn't have much luck..We ended up going to a Tailor that was recommended by the Traders hotel in Penang, it was in the Komtar tower and the name was Jag Men Fashion Tailor (phone number 04 - 262 6993)..We were really worried as we didn't have much to go on as to the quality of the tailor but we'd been travelling all over and realized that we needed to take a chance at some point because we weren't going to end up with nothing..
We ended up purchasing 2 suits and 3 pairs of pants for 1550 ringit (515 canadian)! We brought a suit for him to copy and they did an excellent job and they had to make some slight alternations and did it in the course of an hour. We actually wish that we would have bought more and we just want those of you looking for a place to be aware of this one! You will need to do some negotations for the price (as we did quite a bit) but you'll be really happy with the end results and wish you would have bought more!!!
By the way we did go to the equitorial hotel tailor shop as well and he had much more selection as far as the material goes but he was much less willing to negotiate, and Jag Men had some great material just not quite as much selection!
Happy shopping!
