If you use energy-saving lamps, your white balance needs to be adjusted to that of fluorescent lamps. But light is not enough. You can buy a set of professional lamps on Taobao. It's okay not to flash. Need to surround the exposure. In other words, there should be a light source around the clothes. Or use a whiteboard to reflect light. Foam will do. This saves money.

Then adjust the camera. Aperture and shutter. And sensitive. The higher the sensitivity, the brighter it will be, but if it is too high, there will be noise. Adjust it appropriately.

I wonder if your camera is a SLR? If you have any questions, leave me a message. You'd better tell me the model of your camera
