This checkerboard red denim outfit contains the Corvette of denim jackets. On the other hand, a plain denim jacket (chances are you're 50 ft. from one right now) is like a Honda Civic. I know that because I drive a 05' Civic. Yeah, it's reliable, but I'm not breaking necks.
Men are stimuli-based creatures. If you're one of two dozen denim jacket wearers at a bar, guys literally can't differentiate and will cower in confusion. That's why this checkerboard denim jacket is like a mosquito lamp. Men will unknowingly gravitate towards something that stands out.
