On the one hand I agree with you. However, the combination of "take a picture and we will tell you what to change" plus "if our suggestions produce a bad result you can't return it" puts a lot of the risk onto the consumer. That's fine if the buyer knows what he's doing (or pays a good tailor to comment on fit), but I wouldn't feel comfortable doing it myself. I'd feel more comfortable with this value proposition where the risk shared via a modest tailoring credit. Formosa is $1,900 (after SF discount) and comes with a $140 credit. The KW stuff is about half that price in good fabrics, so a $70 credit doesn't seem unreasonable to me.
This isn't true at all. You have input on what you want to change also. He gives suggestions, but if you feel other things need to be changed, you can change it as well. Also, $70 on a $700 suit is 10% of their total revenue. You really don't think it isn't a lot.
They are plenty of non-MTM suits out there that aren't fully canvassed, MTM, well mad etc, and are 2x the price of Kent Wang.
