All eyes will be on Kate's wedding dress as she walks down the aisle at Westminster Abbey, as a symbol of her personality, and her style.
Westminster Abbey is a vast building and she will look like a tiny speck unless she wears something with some length in a train, or volume.
She's got a very difficult balance to strike between wearing something that people think is worthy of the future queen, but also not overdoing it.
Any designer that Kate decides to wear from here on in will turn to fashion gold, selling out worldwide.
Kate will favor British designers. This will be phenomenal for British designers and the British fashion.
