Models are photographed by photographers.

Hello, don't think too much. Every time underwear models take pictures, there will be many staff around to help them make up and change clothes. I am a photographer. Generally, we just need to be on the scene when taking pictures. Once we move, we will contact the models in the studio, which is only when taking pictures. It's hard to get in touch in private. So you should support your lover's work. Her work is very hard and needs your understanding.
