Here's a breakdown:
* Tailor-made for: This implies that something is specifically designed or created to fit the needs or preferences of a particular person, group, or purpose.
* Example: "This training program is tailor-made for new employees."
* Tailor-made to: This is less common and can sometimes sound awkward. It implies that something is adjusted or modified to conform to something else.
* Example: (While technically correct, it sounds awkward) "This software is tailor-made to our company's specific requirements."
In most cases, "tailor-made for" is the more natural and appropriate choice.
