If you have set it to 1 1 month, it doesn't matter, many people will choose this month. Married in June+10, 5438. It has been raining and snowing ahead, and that day will be fine.
Even if it rains, you can prepare a red windbreaker, which you can wear when you go out, without buttons (red with white wedding dress is fine). In addition, let the bridesmaids prepare white water-based shoe polish in their bags.
I wish you a happy mood!
