My husband's best friend is getting married in July of 2016. I know I have plenty of time, but I like to plan ahead. I just found out that the wedding is a formal Catholic wedding. My husband is in the wedding, so no issue there, but I have no idea what to wear. I've never been invited to a formal wedding before, only semi-formal and casual. I do know it's not black-tie, just formal (which I didn't know there was a difference...ooops!). Any suggestions?? Thanks in advance!
