You can honestly wear which ever style veil you like best. One thing that you have to keep in mind is that back of the dress. If you have any details on the dress in the back and at the bottom you shouldn't cover them up or cut them off. So if you do have details in the back, go with the cathedral veil because then the veil will end after the train and won't cut any of the details off. But other than that, pick the style you like best.
