This is what I would say about Huntsman based on my experience. . .
Quality and construction is first rate. Excellent sewing, finishing and trim. There are a few notable characteristics to my huntsman suit and experience. First, my suit contains a heavier canvas, so even though I chose an 11 oz cloth the suit is very heavy. Much heavier then the italian style suits I am use to. I will say that the heavier construction is growing on me and I appreciated wearing it when I was in NYC this winter. It just has a very substantial feel that I am liking more.
Second, it is a much more closely tailored suit then I am use too. Huntsman has a reputation for cutting a very lean and close fitting suit. This is what I got. As a result, it feels very bespoke. I find that I feel less relaxed in it but more muscular. In fact, one interesting consequence of wearing the suit is it draws commentary on my physique. I've only worn it 5 times publicly but each time I get a comment like "you're taking steroids," "you look strong." I never get these comments in any other suit I wear or if I wear a shirt. I believe it just has to do with the structure of the suit and how closely it contours my frame. It accentuates my broader frame and drop. I'm not sure how I feel about the commentary but I do appreciate the close tailoring of the suit, and feel good in it.
Third, my experience with Huntsman was mixed. I found the staff to be very professional and friendly. A few things conspired to make the process painful though, which has lasted over 3 years and 7 fittings. It was a long distance commission from San Francisco and I don't get to London very often so the process got extended unnaturally where adjustments would be made and then shipped to me. What arrived was always off and I would have to wait six months for them to get to SF to show them in person. As I said this carried on for 7 fittings and 3 years. An easy way to solve this is to live in London. It would have also been avoided if the suit was just right after the second fitting, which it sounds like others on the forum have had the fortunate experience of having. For those who don't live in London though, you need to be prepared for a potential complication like I had as there is no guarantee against it even with the best tailors. (Long distance bespoke sort of puts both the customer and the tailor in an unfair situation and you both have selfish motives for making it work and hope that it will, but there is no guarantee). Another contributing factor may have been Huntsman's ambitious nature. As I said, they do try to cut a very tailored suit, which leaves little room for error. This sort of raises the stakes in the long-distance program. When they get it right, the results are brilliant, but when they don't you go through the ordeal I did.
The one significant criticism I would have of Huntsman itself and not just the overall situation is the apparent out-of-site out-of-mind nature of the firm. In person very professional and polite with an eagerness to give me what I want but once they got home it was as if out-of-site out-of-mind took over. They would tell me that the suit would arrive by a certain date yet I found myself calling two months later wondering where it was, at which point we would go through the same frustrating over-promise/under-deliver process all over again. In the end I probably spent more money on my Huntsman suit in lost time then I did in actual dollars. I realize Huntsman now has my pattern down to make me a very good second suit but in reality I likely won't use Huntsman again for this very last reason.
