Hi guys, my prom date is wearing red D; what should I wear with a black suit to match? red vest and red tie? white vest/tie, red pocket square... silver vest/tie, red pocket square... I really don't know :\\ Any help in pulling this off would be appreciated! Thanks guys. (also what difference from 100% wool does a wool/silk blend make? is it worse/better, warmer/cooler..) What's the shade of red? IMHO, I think you should wear what you are comfortable with. If you wear a shade that you dislike, you will end up not enjoying yourself, nor will you be comfortable. Discuss w/ your date what color, and possible combination you both enjoy! Afterall the pictures are shared right? lol Slight contrast w/ the vest/tie is what I'd go with.
