What is the color that attract girls?

Depending on your age and what different girls like, varies of course.

For a young/teenage look try not too baggy not too skinny jeans with a polo shirt or a checked shirt also do not wear your jeans too low down because what you consider cool is a bit of a turn off for some girls. Also, weird bright T-shirts with bright hoodies and bright shoes is just strange and attention seeking. If you like someone, look cool and slightly edgy- not chavvy.

For older men try the more sophisticated look with a nice white shirt and dark jeans.This always looks great with a tan.

Remember the biggest turn-off with girls is socks in sandals or socks and shorts
