Limited by light, you should choose a large aperture lens.
There is no pressure to flatten clothes. For example, if you shoot a garment with a length of 1m, you can shoot it all by choosing a 35mm lens and returning1m. If you choose a 50mm standard lens, you can shoot it all by retreating 1.5m or so. However, it is limited to shoot the whole model indoors at 50 mm. Using Budweiser to shoot clothes indoors is nonsense, misleading children and shameless and irresponsible recommendation.
In addition, shooting models ... should not choose too wide a lens to avoid perspective distortion.
To sum up, it is recommended to choose Canon EF35/1.4l..
