It's Addicting. Some of you might doubt me, but If you're willing take the challenge and wear two jeans for an entire day, and then tell me what you think. I get called out alot for it however not many people have problems with it even though it's not the norm. I don't see why it would be a big deal as many people wear a shirt and a jacket or two layers. Yet, seeing if anyone else has tried this before?. Just wear two pairs for a day and you'll notice a huge increase in comfort and alot better feel. As far as the double button-up, when wearing black on black, I usually put a pin-stripped button-up as the bottom layer, it has the look of a suit without all the weight, and is alot more casual/dress.
