How can I reduce moiré in clothing product photos, and would a higher-resolution camera help?

I shoot my own garment product photos with a Canon 100D and often see moiré on solid-color fabrics. I’ve tried changing zoom, camera angle, focus point, and aperture, and Lightroom only removes some false color while leaving the texture affected. Since the 100D already has an anti-aliasing filter, I’m wondering why this still happens. For web/catalog use, is there specific gear that can eliminate moiré, or is it more about how the images are processed? Would moving to a higher-resolution camera be worth it?

You are talking about product photographs where Moiré patterns show up. The antialiasing filter of a camera works to suppress such patterns at scale 100% when every pixel the camera has taken shows on the screen. But it is very unlikely that your catalog images are viewed at 100% of the camera scale. Instead of letting the web viewer scale down the images, try doing so yourself in image processing software to the size that is going to be used on-screen. Scaling down usually offers a dropdown menu of "interpolation" options. (Bi-)cubic interpolation tends to work reasonably well when available. The strongest Moiré suppression should be available with a "sinc" or "Lanczos" filter, but that may cause some other artifacts, so you should try out the various available options.

Moiré can still appear even with an anti-aliasing filter, especially on fine fabric textures. The filter only helps at the camera’s native pixel level; once images are resized for web or catalog display, moiré can reappear because of the new sampling pattern.
Based on the advice here, the most useful fix is usually in post-processing rather than new gear: resize the image yourself to the exact display dimensions instead of letting a browser or viewer scale it. When downsizing, try different interpolation methods. Bicubic is a good general choice, and Lanczos/sinc-style resizing can suppress moiré more strongly, though it may introduce other artifacts, so test a few options.
A higher-resolution camera may help in some cases, but it is not a guaranteed cure. For product photos destined for online display, careful output resizing is often more important than changing camera bodies.
