I am still waiting too. My "fitting" was a week after yours, SartorialBuff, in Calgary. Received an email about 2 weeks ago saying they should be in soon and an offer of $100 off the next order- you probably got the same email too?
Having seen some others on this forum receive their product I am less concerned about a scam however 20 weeks is outrageous. I suspect these guys either did not send the orders for some time or are using our funds to pay for prior orders so they're behind all of the time. When I first investigated their website it said they have been in business since 2008 but from this forum and their actions it's pretty clear this was their first go at this.
Also, I have noticed that a suspect "shill" on this forum uploaded photos of a suit which suspiciously looks like one on their updated website. Everything here is adding up to be a bad experience for me, you and many. Too bad, as I was willing to be a strong supporter for these guys in my community of prospect buyers for for them. Now, it goes the other way regardless of if the product actually turns out alright.
