You could also go with a necklace or bracelet that has some neon accents on it like this Harajuku one that I have. It's edgy and has just the right amount of color in it.
Now if you are feeling a little bit more daring, you could always go with some cute neon pumps or a purse like this one by Teen Vogue.
Lastly, neon colored nail polish or hair accessories would also be good things to try and it wont be so hard to pull off.
Whatever it is that you decide to try, just remember that the only way it will look good is if you exude confidence!
