I bought this yesterday, not a fan of black denim. black denim looks like formal pants.

Uniqlo selvedge quite comfortable though. i like the rough material. see if i can make till like this
The recent batches are mostly with spandex mixed in and zip fly. I was lucky to hit pretty early series back then still release in 100% cotton with button fly.
Black denim if worn well, the fades can be even more interesting than the usual indigo counterpart. You can google black denim fades for reference.
No right no wrong, denim is supposed to be comfortable and easy to the person wearing so long you enjoy it.
