I have to disagree with much that has been written on this thread about custom versus RTW. I think people are trying to characterize a moving target. The longevity of better garments is not due to their construction, but their fabric. Most seams that loosen for example, can be easily repaired. Even linings can be sewn or replaced (I had to have a lining extensively repaired on a coat that is 30 years old for example). But fabric that develops a shine or becomes worn, cannot be fixed. I do not think there is any reason a custom garment will last longer than RTW, except perhaps because you treasure it more. On the other hand, I also disagree that custom is an "advanced topic" that one should only try after much experience with RTW. As many who have followed my adventures here and on Ask Andy, this was the same objection posed to my acquiring bespoke and everyone who posted, even in this demanding bunch, complimented my suit from Centofanti, my first. I just had to do a bit of research so that I had a vocabulary with which to make requests when I ordered. But my second order was effortless. I think the answer is, it depends. If you are a difficult fit and RTW never fits you even with alterations, then go for it. But RTW will almost always be cheaper for similar quality of fabric. The cheapest jacket bespoke will not cost less than 1500 dollars, except a Chan-like deal. The best jackets in the world from eBay sellars will cost less than 900 dollars. FOR ME, someone who is fussy about pants fit but whom some models fit well, RTW works fine, more for sportjackets than suits. But ordering bespoke from Centofanti, admittedly one of the best tailors in the USA by common accolation, has been an unbelievable pleasure. I can pick the most incredible fabrics and get garments one could NEVER find in a store at ANY price. We talk casually as if one can purchase ANYTHING RTW, when this is simply not true. Double-breasteds are fewer and fewer. Subtle patterns that have life are few and far between. If one wants ticket pockets or special features, you are even more out of luck. FOR ME, a COMBINATION is perfect, because both have their virtues. When I post pictures of my double-breasted herringbone from Centofanti based on the De Sica jacket whose picture was posted on London Lounge, you will see what I mean.
