I’m v traditional when it comes to weddings ( absolutely no to white or black) but this dress is v pretty and the spots are vivid , so I can see why you like it. However, unless ( and probably even if) you wear a jacket with it , it will still definitely shout loud in the wedding photos , and depending on the bride - you risk upsetting her ( and certainly any older/ more traditional relatives). Personally I wouldn’t risk it 🥹
