If moire effects occur regularly when shooting patterned fabric or leather, and if AA filters are only a partial fix in some cases, how do fashion photographers cope with moire effects?

There are a few ways to deal with moiré and none of them is a guarantee in every situation:
- Moiré adjustment tool/brush/filter in your post processing tool(or manual techniques with similar impact, manually blur areas of the image with moiré)
- Stop down your aperture to introduce diffraction
- Use a higher resolution sensor
- Have the model use a different patterned garment
- Use film instead of digital mediums
A professional fashion photographer likely is using a medium format high resolution camera and has the option to shoot in a studio with very small apertures and bright lighting that will introduce the necessary amount of diffraction to limit negative impacts of moiré.
Keep in mind that a fashion photographer likely has a great deal of control over the scenario and can make immediate changes if necessary. For example they can view images immediately on a monitor and adjust the models position to a more desirable one if moiré is excessive.
