Bridal ponytails

Ooooh I love this idea. I just did a quick-ish search and I tried to find ones for "real wedding" and was struggling. BUT what you could always do is look for a YouTube tutorial and give it a rough go yourself, put some hair pins or hair vines in, and see if you like it enough to do a trial with your hairstylist?

Also, most hair trials run through a series of 3 styles that kind of build off one another. If you tell her you're interested in a bridal pony, maybe she can work that in as your final style instead of the usual low updo?
