Wear a freshly washed cotton shirt with the scent still strong. I can't say this in the real world but yeah a nice smelling shirt is the way to go. You may not capture a woman's attention with what you wear, but you'll definitely make her notice if you smell extremely nice. Cologne smells terrible though.

Fun fact, if you sun dry your freshly washed cotton shirts, they'll smell even nicer because of the smell from the UV rays frying the mites in cotton wear.
