I think that it all depends on your facial shape. If you have an oval face, it could work out really nicely. However, if you have a round face, like me, it looks hideous. The center part splits the face in half making it look rounder.
Center is back?! It's fine. I like it. But it still depends on how you style it. For some center and straight is fine but for it may not. But for me, I prefer it to be with volume. Because I'm on the chubby side, center is good but if it's straight, my face looks chubbier. =)
