So I'm getting a gray 3 piece suit and from what I've read here it's a good idea to match the back lining of the vest with the lining inside the jacket. The suit isn't for work or anything and I like a loud lining so I was thinking perhaps a dark purple color. But then the back of the vest will have to be the same color too. I probably won't wear it without the jacket as a default, but there will be times when maybe I'd like to take the jacket off and roll up my sleeves. Would this colored lining on the vest back look bad? I also have the option to make the vest back the same fabric as the suit/vest. But I don't know if that's a good idea. Also, it's really hot here in Texas. Here's an image I photoshopped as a reference. Thanks guys!
