Ceremony: At the church it is formal/semi-formal to show respect for the bride and groom's beliefs. Reception: Medieval Fantasy (Think Lord of the Rings, Skyrim, ACOTAR, etc.)
After the ceremony there will be pictures done with family and friends. Additionally, the reception venue isn't open for decorating until noon which is when the wedding is happening at the church. So some of the time is to provide ample time to have everything ready for guests at the reception.
