The rehearsal dinner allows you to be with those closest to you before the chaos of the wedding day. With that being said you should feel comfortable and at ease with what you wear during the rehearsal dinner so you can focus on the loved ones around you. Whatever you choose to wear let it reflect who you are. After all, your future husband is marrying you for you, not the clothes you wear.
