I think some of you are missing the point. He's having a blazer custom-made exclusively for business use. He doesn't HAVE to hope nobody notices its casual details. He can just not get them in the first place.
You know, you started off as though you might have had some barely detectable trace of a valid point (even though it did seem like you equated being grossed out by sock-sniffing stalkers with homophobia or rape culture) but now you're acting like you're the only one with a moral compass and you look like a shrill lunatic.
I like to think of it as a heavy casual fabric. Typical chino fabric is around 7oz weight and this stuff is more like 10oz so I absolutely wouldn't recommend it for hot humid environments. Of course it works for colder weather but I also think it has merit as a travel material due to its toughness and I plan to make dress cargos out of it (I travel a lot and am well on my way to having an entirely separate wardrobe just for travel). You could make a nice business casual...
That is not their default waistband. I always go for their standard waistband and it is tastefully sized with traditionally placed belt loops.People are specifically asking for the cummerbundy waistbands, drag-chute pleats and nipple-high rises that you occasionally see here. I know. Me neither.
