As someone who is trying to dress more stylishly and more "mature", you might say, I haven't really been able to find a solid yes or no answer to this question:

Can you wear a waistcoat with jeans if it has a rayon sing backside?

I have scoured numerous sites with waistcoat tips, history, and style guides...but this is never one of the "no-no" rules to wearing one casually.

I saw on ONE forum site people saying not to wear a shiny backsided waistcoat casually with jeans, but most were saying dont do it if you plan to wear it unbuttoned with a v neck, or something along those lines.

My question is, would a black waistcoat with a semi shiny back be fine to wear casually with jeans, a solid button up with the sleeves rolled up, and casual dress shoes?
