I have recently found a site in Singapore that sells fabric online.
Koh at HST is very helpful, drop him a line and Im sure he will be honest in his appraisal of that linen. Most of his stuff seems pretty nice, although people have commented earlier that his shirt cloth is overpriced. Im sure its nicer than you will find at your local Spotlight anyhow
Ive generally found the prices in his clearance section to be very good, elsewhere just standard.
In general is it better value buying your own fabric and taking it to your tailor to be made up.
People are questioning the logic of this over at AskAndy now. For some reason I cant connect to it at the moment, but Ill edit and drop in a link when I can. My understanding of it is that tailors get a tradies discount on cloth and then mark it back up to retail-ish, before selling it to you plus a reduced fee for workmanship. BYO cloth then you take away his percentage on the material and he will charge you a higher fee for his services, meaning that you end up most likely paying more unless you can get a fantastic
deal on the fabric. It would want to be a fantastic deal anyhow to remove your touch-and-feel aspect of evaluating it and the advice your tailor can offer. I'm Australian but live in Vietnam, where the tailoring is so cheap and the cloth is so crappy that it makes sense for me to do it that way, but back in the real world I'm not sure youll see much benefit.
