Red is the color of Valentine Day and the use of this passionate and romantic color should be a major theme. This can be reflected in your attire. A white dress with red accents and an old fashion style is very romantic. The bridesmaid dresses can be various shades of pink and red as well. Even the groomsman could wear red ties with pink boutonnieres. A color scheme that utilizes red and pink, and lots of red hearts in the decorations will reinforce the romantic theme.
Rose would make the ideal flower for the wedding. Flowers are romantic and you are going to want a lot of them, but roses can be very hard to come by and quite expensive in February. It might be a good idea to explore the possibility of alternate flowers that can also be found in pink and red. Tulips, hydrangea and freesia are a few possibilities.
It is another good idea to get your guests involved in the idea of the romance of the wedding. One idea is to have all married couples stand during the ceremony and reaffirm their love for each other. You can also follow the theme of romantic love by introducing famous couples of the past. One way of doing this is at the reception. Rather than numbering the tables or placing name cards, you can name each table after a romantic couple from history like Romeo and Juliet.
Valentine Day is the day that celebrates lovers and romance. A wedding on this day will make it a special day for you, and there is an additional advantage. In the years to come, you will have a little help remembering the date of your own anniversary.
