FI's sister is getting married on Sunday. The only really "fancy" coat I own is white. Would it be tacky to wear the white coat? My dress is black and I would be wearing it basically from the church to the reception and having it checked. I also have also heard his mom mention pictures but it was never really mentioned if I will be in any of the formal pictures, some of which would be outside. If I were in the photos would I be wearing the coat? Obviously if I wore the white one and was in formal photos I would remove it. Just trying to figure out if I should wear one of my more casual coats instead of the white one or if it is acceptable to wear it and check it.
