My guy has the "engineer chic" look. Basically, its whatever you can throw on before you're 7:30 am circuits class.
His style is usually khaki shorts and a tshirt, or jeans and a tshirt. Sometimes he throws on a button-down shirt over the tshirt just for variety.
Its simple, basic, and not prissy at all. I don't know if I could deal with a guy who worried too much about clothes. I kinda enjoy it when he asks for my help
One thing I CANNOT stand on a guy is jean shorts. They irk me to no end - something just looks trashy about them. Same with tank tops on guys. I also dislike jewelry on men. A wedding ring and a watch is all my guy should ever be wearing.
