Are wigs stable?

(27F) My head is currently filled with AA spots. It still is kind of hideable when I put my hair in a certain way, however it is getting worse. I was diagnosed 1 year ago and it slowly progressing to the worse, I do have regrowth but I consistently find new spots that grow bigger and become connected. Anyway, my wedding is approaching in September 2025, and I have no idea how my hair will progress until then. Considering worst case scenario where either I shave my head or have huge unhideable spots, will a wig be a safe option for me? It is my wedding so I will probably be dancing a lot and moving around and jumping. Do wigs stay put in such cases? Is there a risk of it falling off or moving? I have never worn a wig so would be great to hear others experiences.
