Body. No one likes a boy who smells of sweat and feet. If you can take a bath after exercise every day, cut your nails neatly and shave your beard cleanly, it will definitely add a few points to your face value.
Clothes. Dressing can be less fashionable, but it must be clean and refreshing. I like the boy whose clothes are always clean and tidy, whose shoes are spotless and who still smells of laundry detergent. Such a boy will always leave people with infinite goodwill.
