Got my suits from Sierra Trading Post (2-day fedex). I ended up ordering one of the three buttons in a 52 since I was skeptical of the 54 to 42/36 conversion they had on the website. Glad I did, the 52 fits much better right (will need to get it taken in in the middle a bit, but I always do). Oddly enough, the 54 isn't far off at all in the shoulders, but is too long and baggy in the middle. Plus - I like the pattern on the 3-button better. Only downside, $1,000 before the coupon, $800 afterward - still a good deal in my book. Quality definitely seems top notch. Just a titch below the Attolini in my book - main things I notice at first glance, Attolini has more "precise" (not sure how else to describe this) stitching along the edges of the lapels (the stitches sort of look like little dots), and I vastly prefer the button-fly pants of Attolini (obviously this is not a criticism of the Isaia per se, as 99% of suits sold out there probably don't have this type of pant fly). All in all, very satisfied with the purchase.
