I've been lazy on getting my dry cleaning done, and now have limited options. this shirt has the best fit out of what's left. it's purple. I plan on wearing a darker charcoal suit. what color tie should I wear with it? I read navy would look good? maybe just go with no tie and leave a button or two undone? I also conisdered wearing the shirt with darker grey slacks and a lighter grey v-neck sweater and no suit jacket. thoughts on that, too?
