The arch-shape is a classic one, even though surprisingly many brides-to-be have not heard about it. I guess it's because all the wedding flowers catalogues nowadays are filled with complex, often futuristic and one-of-a-kind creations, which are always great to admire - the way art is - but not really ideal for a lot of brides.
Anyway, the arch form is perfect e.g. for 20's style dresses or any dress with an empire-line, so if that's what you have in mind for your Big Day - this style will suit it really well.
