Dat Zegna. Super recent based on the stitches holding the tag. I also found a Zegna SC with the sleeve basted as such. There were no buttons in the pockets, but I'm sure I could source some smoked MOP to make the jacket pop. My competent, but limited, tailor doesn't do functioning buttonholes so I've left the sleeve as is for now.
I honestly think the guy must have died, because I'm fairly certain all of the stuff was his and was all mint or unworn. I left a Zegna soft SC that I may actually go back for as it was a nice brown and well made.
Re: sleeves. Weird, right? This one has buttons attached so I wasn't sure if they leave it as an option or whether he declined because it cost more
The only button holes that I've had done were at the store I bought it. I didn't ask which tailor they used, but the work was fine I'd say. I need to get buttonholes done on a jacket as it's without them entirely and I'm pretty sure my tailor does them, but I'm sure he'll be expensive.
