i have very long hair and my fiance wants me to wear it down. the back of my dress is low cut which i love but my hair completly covers it, although most of it will be infront of my shoulders. But after the last couple of 90 degree days, im worried im going to be so hot with my dress and hair down etc. the only time we will really be outside is to go to and from hair salon, church, reception, and outdoor pics after the ceremony. thoughts???
