Red, And More Red

Back when it was really cold, I wore my ebayed Gieves & Hawkes DB peak-lapel 2x2 keystone suit (pattern here) with an ebayed LL Bean red cardigan (basically Mr. Rogers's famous red sweater but with buttons) and that fun bowtie with the red reverse (not my first experiment with that, either). 

Maybe I'm overselling my own theory of clothing, and you'd have to ask my coworkers how they felt about the outfit, but I think even a Mister Rogers sweater can be appropriate in context.  A DB jacket and a bowtie tends to say, "Why, yes, I did this on purpose," not, "Why, yes, this is my first rodeo.  How could you tell?" 

That said, I wouldn't wear this particular outfit before Christmas.  Holiday outfits--even those famous Ralph Lauren red tartan Christmas trousers--are an extremely dicey affair, requiring sensitivity at an atomic level to one's partygoers' personalities.
