I like this place.
I've tried on the Napoli for $469 and Jort for $999. The sizing/fit of the two isn't too far apart, with the Jort being slightly more trim. I THINK the Jort is fully canvassed where the Napoli is half, and there is a noticeable upgrade in some of the materials for the Jort. For some reason the Jort doesn't even appear on the website. I'm 6-1 and about 160 and the 38 R fits very well except for as usual too long sleeves. Watch out as they have surgeons' cuffs which will limit how much you can shorten. The trousers fit perfectly - can't remember if they were unfinished or just very long to give you the option of shortening and/or creating turnups.
I also noticed some variance among the fit of some Napoli suit jackets I tried on, which for the budget-minded should be borne in mind in order to assess the additional cost of alterations, especially for those ordering online.
I don't like their website much and they have a much broader selection in the shop. If you see something you like you should jump on it as they get new stock in all the time and don't have sustained 'lines' in terms of materials and colours, they tend to do shorter seasonal runs. Some of the materials I saw there a couple of months ago weren't there last week.
Still, even their cheaper Napoli suit is better made IMO and has a much better variety of colours and materials than say J Crew which are similarly priced or maybe even more expensive at retail. BTW I asked the SA and they don't do sales. They plan to move their old stock to the new store in DC to make room for new stock in NYC.
Hope this was helpful to the prospective SS customer.
Very helpful, thanks. How does the quality compare with a Brooks Brothers 1818?
