years ago i would switch the part from left to right, right to left, whenever i felt my hair needed it. since i've been cg, tho, i've kept it parted on the right side, sweeping over to the left. i do change where the part is, sometimes slightly more than off-center and other times more dramatically parted to the right. as rustina said, my hair also curls away from my face on the left and comes around to my face on the right, so i'm thinking it's the way it curls on my head that make it seem this is the way that works best for my hair.

you should have fun with your hair and try different things. just try switching the side part on your own and see how it goes. if it looks good, then wear it that way and tell your stylist you wanted it parted that way.
