Well, it's a large format plaid, with a fairly quiet colorway. And everything else you're wearing is practically mute.
Suit: Let's have fun!
Shirt, tie, square, shoes: Go to your room. For you, there will be no supper...
The effect is to make the suit like one of the cut-outs in my avatar, something swapped in or out without relation to anything else.
I like the suit, but at this point, you're not wearing it -- it's wearing you.
