Coz I don't find any that I look good in and that I like. They can be nice on others, but on me I feel they are boring.
I think I'll look more in the direction of bolder patterns, like checks. They are more interesting and I have seen so many nice in this tread that I rather explore that road and not the plain which I've been traveling the last years.
Often, the boldest thing to wear is also the simplest. Think Hemingway, I guess, though I'm not sure if literary comparisons translate all that well.
