Second guess you wedding dress?

Have any of you had second guesses on your wedding dress? The one that I had the most emotion too is something I didn’t ever envision myself wearing. My mother and sister were the only ones who were with me and I tried on 4 different dresses. I did buy the one in the photo- it makes me feel so elegant! But is it sexy? Idk haha fuck this is hard! But, I’m afraid it isn’t the “one” maybe I’m over thinking it. But have you ladies experienced this? My wedding is in July so I have time to look-considering looking again before I alter my gown and can’t exchange it....

Thank you!
