Although some weddings are in more casual dress and also bearing in mind LGBTQi weddings as well, most bridal dances will aim to showcase the bride in her beautiful wedding dress (and the groom in a dashing suit).
It's fair to say that a wedding dress is not designed for dancing. Some have a train, a hoop skirt, a head piece, perhaps constrictive, and may even drape to the floor at the front. Essentially a wedding dress is designed to walk forward (with assistance).
We design your wedding dances to cater for the design of your dress (as well as your shoes and other factors). Normal dancing has the woman going backwards - something that we minimise in wedding dance design.
