Spoke to Narin many times about suit construction. Something always made me hesitate. Depending upon the fabric, the full canvass will cost 10,000 baht premium otherwise he will fuse. After having had 6 suits made by 4 tailors all over Bangkok I had the best suit made by Tanika on Sukhumvit near Asoke BTS, close to Narin. Full canvass, hand sewn, great tailoring, exquisite workmanship, bone buttons, secret pants pockets with a very long list of everything I wanted on jacket and slacks, and perfect fit for 38,000 baht. What's the downside? They will only use their fabric. The suit took a long time, about 5 weeks with many. many fittings. (This is not a bad thing but if your time is limited, be warned.) They'll try to get you to purchase a 2nd pair of slacks for the suit, which to me is unnecessary unless you're a real slob. They are inflexible about price, so forget about bargaining.
Their selection of fabric is quite extensive and they have fabric in all price range. I pleaded with them to make a suit from Pal Zileri fabric I bought and they just refused. They will make a fused suit or an unstructured suit with no fusing using less expensive fabric at about 18,000 baht. They have assured me the fittings will be the same but they did show me the tailoring differences. The hand ticking around the lapels and pockets and flaps which was so incredibly meticulous on my 38,000 baht suit is different on the cheaper suit. It's more pronounced and although they assured me it is done by hand it's a completely different technique. When I asked if they would use the expensive ticking for a premium on the cheaper suit, they refused. Also they only use one fusing material and they said it was on the thick side, so if you want a lightweight jacket that moves like butter, you better check out the samples in the store.
Despite their inflexibility about the things I mentioned, they were very flexible as far as design and incorporating all of the elements in the jacket I wanted. Soft shoulders, no vents, tapered waist and they didn't mind at all revising the silhouette of the jacket as the fittings progressed. Also the slacks I requested were reversed pleats, cuffs, button fly and elastic waistband and secret pockets in the waist and bellow pockets on the slacks and they were only too happy to satisfy my whims. I would definitely have them make more suits for me in the future. While I don't fancy paying 38,000 baht and up for suits I realize that in the world of bespoke that's a drop in the bucket and it is in my range of affordability.
While my friends tell me I'm overpaying when the hundreds of tailors around me are charging 5-10,000 baht (some even less) for suits that are turned out in days, I realize the difference in quality and I appreciate the difference. I know that my suit will last a long time because I'm using a style which will be fairly timeless, at least for my lifetime. So If I get one suit made every other month for the next year, I'll have a lifetime of suits and they'll be recognized as special.
