What do girls think of guys in white colour running tights?
Where I live, near Boston, there’s nothing wrong with guys running or jogging in tights, and it’s common in cold weather. Wearing white a night is very sensible, and I think it would be obvious to most people white is for visibility. Also, for activities like running or cycling, function takes precedence over fashion. One of the previous answers mention something that is important to remember about white. White does get transparent when it gets wet, so if there’s any chance of that wear some shorts over them. Don’t worry about heads turning. Just because someone notices you doesn’t mean they disapprove.
