Actually that's the one thing that concerns me the most....there are so few reviews of propersuit. You'd think a company that's been in business for 2 years would have more reviews out there. More photos of actual people wearing the suits. The deal seems good, I checked around and local tailors do the same thing in Seattle but start at about $900 vs $650. Propersuit seems to win on price, but I would hope the local tailor offers some tweaking of the suit once it arrives (if needed) I believe I'm on my own for any alterations from proper.
Until I read your post I had never heard of Propersuit. I think you're comparing two different types of services here even though I would say the suits come form similar places. Indochino are an online service with their suits made in Shanghai while Propersuit appear to have a more personalised service. They seem to arrange to have you measured then arrange the production of the suits.
To me the only reason I'd go with Indochino is the price. However, $650 for a full canvas suit made with decent wool with them providing an onsite service looks very attractive. I think it's the way I would go
I have dealt with the guys at Proper Suit, they were very professional and I'll be ordering another suit from them this week.
No full shots unfortunately, but you should get a sense of the fit, which is spot-on.
