For a nude photo shoot, you should wear something that is comfortable and lightweight. A simple cotton tank top, shorts, or a romper would work well. Choose something that is easy to move in, so you can change poses quickly and easily. Make sure the fabric isn't too thick or bulky, as this may show up in the photos. Avoid any pieces with busy patterns, logos, or bright colors. Opt for something in a neutral color, such as white, grey, or black. Finally, choose something that is fitted and that you feel confident in.
