Wedding Dress Shopping

I’m getting married in November and just started looking at dresses today. I tried on about 12 and found out I’m super picky. I feel really discouraged and like no store is going to have the type of dress I want. I find all these ones on Pinterest but they are all sold only in the UK or Australia. I’m looking for a really dramatic cathedral type dress that has a really long train (probably ball gown with a long train). There isn’t that many bridal shops in my city so that makes me even more nervous. Did anyone else have a really hard time finding their perfect dress? How do you know if it’s THE dress

Here is one I liked but I didn’t love. I don’t want to settle for something I’m not in love with.
