''Hello I need some anonymous help! I'm getting married on Friday and have a wedding dress, however, I don't think I'll last the entire day and night in it as it's not the most comfortable thing I've ever had. I'm a big girl and need a nice dress, preferably long that doesn't cost a fortune that I could maybe change into. Could you post this to your page for ideas from everyone please xx'' JuneBridals low-v backless outfits for formal
