Guys who wear tennis shoes
I would say, yes.. but it depends on the event, the reason of the event and who's there.. Specially, if you want to make an impression, or not. If you work in high tech and it's your buddies..well, you know you just show up as yourself.
It also depends on the time of day.
Are you a guy? A girl? A woman?
All of these things matter... If you don't want to say more, just remember that you could have tennis shoes in all sorts of colors. Make sure you're matching and that your tennis shoes don't look all scuffed-up. You could get creative with your socks.. You could wear a blazer and a scarf.. But if you're going because you're hiking.. or playing in the mud.. then. that's a different story..!~IR
