Lindz! Go with your instinct on your hair...you don't want to look back and wish you had done something else. If you wear your hair down alot, maybe you should wear your hair down or half up on your wedding day too? If you aren't 100% happy with the updo you don't want to look back at your pictures and feel like you don't look like yourself or aren't happy with your hair. Do whatever you LOVE and whatever is going to make you happy.
I wear my hair down always (except for the gym). I had my trial and the girl did loose waves with a half up hair style. I did not like it. I felt like it was tooo bride-ish. So now I think I am wearing my hair completely down in curls. Ill pull just a little bit of hair back for my veil.
