According To Jason Derulo, You Should Never Wear Fanny Packs Unless...

Jason Derulo flashes some peace signs as he arrives in Sao Paulo, Brazil on Wednesday night (November 12).

Just recently, the 24-year-old singer chatted with People about his style game and the item that people should never wear.

“If you’re going jogging, or hiking or something, but not any other time,” Jason insisted when fanny packs were brought up. Noted!

Jason added about his own style, “If it’s daylight, I do a lot of sporty wear. A lot of baseball caps, gym shorts, a lot of sleeveless shirts…My sense of fashion changes all the time. When somebody looks at you, they should be able to tell what kind of personality you have. My personality is a little loud.”
