Would hose #2 and flashes #3 be a disaster on outfit #1?

I do see the slanted kilt pin as suboptimal.

My n00bness is showing I am sure; I must have missed something in the reading assignment since MacMillan of Rathdown didn't mention hose #2 with outfit #1.

Maybe I did see "dark or argyle" hose for formal wear. Dang it.
