Groom wearing wedding dress

Im a gay man and have decided to wear a dress for the ceremony im extremely feminine and grew up in a household of only females so it kind of feels right for our wedding and its now starting to hit me that it may cause alittle friction during the wedding because not only does my fiancés mother not like men doing or using anything feminine a couple in my family aren't the most supportive especially of breaking gender norms im not going to change my mind of wearing a dress but i may have a talk with the people before hand as for the dress itself im going to be making it myself for a few reasons reasons being 1 im only 5 foot 2 inches so dresses in the style I like would be too long for what I want sense I want it right Below the knee 2 being even tho I'm a guy I have a more curvy body which runs in my family for both the men and women to have a more curvy body mine being wide hips large thighs and large bum with a smaller waist so if I were to buy a pre-made dress I would haft to get it larger and loose a large amount of detailing 3 being im extremely picky with my clothes and I want the dress to have aaaaaaloooooot of pearl detailing and a tooooooon of lace and for it to be pink and white and a lolita style how should I go about talking to these people about me going to wear a dress
