Hi all. I just received an invite from a friend, whose wedding is at a church at 1pm, with the cocktail hour beginning at 5pm at a hotel. The reception card says "black tie welcome." I'm good with the dress etiquette for the reception, but I'm curious about for the ceremony. Is it appropriate to wear the same (on the formal/conservative side) cocktail dress to the wedding, or should I wear something more akin to 'Sunday Best' to the ceremony, and change before heading to the reception?
