If your wedding is a glamorous one, choose a cathedral-length veil.
If you want to create more of a modern look, go for a shorter one.
If your dress has a lot of detailing such as lace or sequins at the back, choose a one tier veil, it is a sheer veil that won’t hide the dress.
The detailing on the veil should complement the dress, not overwhelm it. There can be sequins, ribbon, lace adornments on a veil.
Bell shaped veil of a fingertip length is perfect for a mermaid dress and a one tier veil will complement a ball gown dress.
