I did a quick read of your prior post, and it looks like you managed to trigger the 2 biggest landmines on this forum: black suits and black shirts.
Much like what you experienced in your black suit thread, there isn't any love here for black shirts either, because they rarely, if ever, look good with a suit. That said, certain fashion house like Dior are known for the black on black on black, so what do I know. If the black shirt is meant to be for work, I can tell you that yes, like a fashion-forward black suit, it would kind of stand out as well.
In any case, this is just friendly heads-up that you may experience a lot of snark.
Sorry, and welcome to SF.
