The easiest hairstyle changes for an idol to do is to go from wavy to straight or vice versa -- and man, they look good with both, hands down!  However, there is always a preference for one or the other depending on the face shape or the general vibe.  While some people look classier and more elegant, others look more youthful and cute with the wavy hair look. On the other hand, straight hair can be the more typical, girl-next-door look that never gets old.  Some people prefer the wavy hair for more volume and a smaller looking face while some prefer long hair for the simplistic and classic beauty.

Check out these five female idols below and decide for yourself which look you prefer on them!
