For commercial clothing photography, a custom profile is generally worth using when accurate color matters. The key point is that color can change with the lighting, so each lighting setup should be profiled if you want the most reliable result.

A common workflow is to place a ColorChecker in the same light as the subject at the start or end of the shoot, then use the profile created from that reference during processing. That gives you a known, consistent baseline rather than relying on a generic Adobe profile.

Adobe Color or Adobe Standard may look more pleasing to you, but they are still general-purpose renderings. If the client expects exact color, the custom profile is the safer choice.

Also check that your raw processor is using the current process/calibration settings, since those can affect color too.

In short: for product and apparel work, profile the camera for each lighting situation when color accuracy is important; use generic Adobe profiles only if you prefer their look and strict accuracy is less critical.
