Svenn,
Yes, I've been lurking here for quite a while, I even read the forum for a good while before joining. Actually I mainly joined so that I could filter out the NSFW avatars and signatures in peoples posts. I work in an open plan office and having titties bouncing around in peoples avatars isn't great when I'm surfing from my desk. Especially not in the middle east

I responded to your post because I have direct experience with the tailor you asked about and it seemed possible that there was no one else on the forum that would be better placed to answer your question.
I certainly don't have any axe to grind against Narin, and I blame myself for the stylistic choices in the suits + jacket that I had made there. At the time of purchase, I didn't really understand what I was buying and didn't know what to look for. When I walked out of the shop I was happy and wore these suits for more than a year with pride. Only later when I became a little more educated did I see that the style was dated, the cut was shapeless etc. As I didn't specify the shoulder style, gorge, armholes etc it would appear that the style that I got is the "house" cut.
One of the problems with having clothes made in Thailand is the quality of cloth on offer. Duty on cloth is (at least it was when I was over there) high, so the range of cloth is limited and mostly poor quality local or Chinese woven. Maybe if you take your own material you will have more luck?
For the price I paid at the time, for 2 suits + extra pants I could have had one suit from Chan + a good chunk of change towards a second. If I knew then what I know now, this is what I would have done and I'd probably still have that suit in the rotation.
What? I'm humble too, but there is no reason to feel ashamed because you are wearing quality clothing that if looked after will last 10 years or more. Actually I think of it as frugality, I'm getting a good (ok this part is subjective) product made out of quality materials using quality construction techniques for a great price (less money than I would be spending in the UK). These clothes are supposedly timeless so providing I look after them they will last me a good long while.
