Bride
Formal Day
Floor-length gown with cathedral or chapel train in white, ivory or pastel. Long veil. Train is optional in a full-skirted ballgown. Gloves mandatory if gown has short sleeves or is sleeveless. Shoes match gown. Bride carries bouquet or prayer book.
Formal Evening
The timing of the day formal wedding is up to six o’clock. After six o’clock the formal wedding becomes an evening formal. The bridal gown is the same, however, although, in the evening, there may be more extensive trimming and more elaborate fabric.
Semi-Formal Day
A white, ivory or pastel floor-length or ballerina gown worn with an elbow-length veil. (An informal wedding would either omit the veil or include a very short veil. A hat or flowers in the hair are an option.)
Semi-Formal Evening
The choice of gown is the same as for the semi-formal day wedding, although the gown detailing might be more elaborate.
Groom
Formal Day
One choice is a cutaway coat in grey or black with striped trousers, grey waistcoat, wing-collared white shirt, striped ascot. Another choice is the shorter jacket with striped trousers, wing-collared white shirt. These days, the tuxedo also is worn at the daytime formal wedding.
Formal Evening
Black tuxedo or dinner jacket, black striped trousers, coordinated vest or cummerbund and bow tie, although other tie options now are acceptable. For a very formal wedding, black tails, white tie and accessories.
Semi-Formal Day
Grey or black jacket with striped trousers, grey vest, white shirt, grey-and-white striped tie, although currently there is relaxation in choice and colour of vests and ties.
Semi-Formal Evening
Dark jackets in the winter and lighter colours an option in the summer. Matching or contrasting jackets and trousers. Tie to match vest or cummerbund.
