curious....who is making the suit for you? a grey flannel (esp in 3 piece.) is a real classic, one i've considered for a while.
W.W. Chan & Sons Tailors in Hong Kong. http://www.wwchan.com/about.htm
I was in Hong Kong last year for 8 days, and had them make me some suits. They are a quality bespoke tailor as opposed to the 24 hour suit shops which are everywhere in Hong Kong. Trousers are made mostly by machine, but the jackets are constructed mostly by hand. (beautiful roll of the lapel, and absolutely flawless fit.) Fabric selection is pretty much unlimited with choices from the best English and European mills. I went through 4 fittings, and was quite happy with the results. Quality is very high and fit is perfect, but the prices are quite reasonable. I paid about $850 for a very nice Summer weight tan suit made from Super 150s wool/cashmere blend, if that gives you any indication. Style is conservative English. Very fitted but comfortable. I ordered an ivory dupionni silk suit from them this Summer, made from my pattern as opposed to actually getting fitted again in Hong Kong. It also fit perfectly, even without the benefit of the fitting sessions. (They shipped it to me in a tiny box, however, and it took me forever to get the wrinkles steamed out.) I'm probably going to get most of my suits from them, as they are significantly cheaper than my Anderson & Sheppard suit, and seem quite close in quality. I've also been ordering my shirts from them. Again, they have an almost infinite fabric selection. I just give them some vague descriptions of fabric type, pattern and color. They send me some swatches, and I pick out what I like. So far, I'm quite happy. We'll see how the new suit works out. Kai
