I love adding an electric brightness-ness to my outfits. I have a section in my closet dedicated to Neon colors from shirts, bottoms, accessories and shoes. Neon steals the spotlight on and off the golf course, but when you are on the course, it is much more socially appropriate.
There are many athletic brands that have now expanded into neon colors, trying to give their brands and clients a vibrant look. Neon-on-course will always be in style. Take a risk and go with a neon outfit, see how it makes you feel when you play.
