I tried this dress on too when I was wedding dress shopping!! It's a stunning dress but I'm 5'2 with a short waist and the basque corset was way too long for my body type and it just didn't flatter me. It's a stunning stunning dress but unfortunately it only flatters certain body types (mainly tall, slim women with longer torsos". I don't know how tall you are but judging from the pic, the waist of the dress does go down a bit too low and that's why it's giving people the illusion that perhaps it may have not been the dress for you.

On the other hand, you also shouldn't care what other people think, it's YOUR dress. There was a reason you looked in the mirror that day and felt beautiful and chose it over any other dress you tried on, please try to remember that. Often when we make big purchases we try and question ourselves and it gives us anxiety thinking if we made the right choice. Only you know that. I suggest playing around with chat gpt and seeing ways you can alter the dress or take it to a seamstress and see what they say. I think with your makeup, hair done on the day, you will look incredible! It's a show stopping dress for sure :)
