I know the normal is a white colored dress shirt with black suit, but what other good looking shirt colors are there? Small checkered black and white with a black tie was my thinking. Or something with a pattern and some color, but don't know. It's for a friends wedding. What are some of suggestions?

Thank You :)

P.s. if it helps I'm a young male, mid 20s

I always have pimples but for a week or two they will go away and then come back for a couple of months, and the pimples always happen in the exact same spot. I only have them on my for head and in between the eyebrows. Is there a home remedy to help cure this or an over the counter solution I can get. Also I have scars from the pimples I used to have because I popped them, is there a solution to get rid of these scars. Thanks for all the help.
