You can put any item of clothing on in The Tailor and it will do something. The problem is usually a result of boots or whatnot not sitting in the right place over the other to be properly copied. As a matter of fact, you can even use non-clothing if you want to. However, when the body parts don't match up well, copying something won't work too well (though sometimes FBMs work fine regardless if the figures match up closely enough). This means that if you really want to, you could load up boots for the P4 male, fit them on Mike as closely as possible, and export new geometry, then point th new geometry at them (the parts are the same, as Mike and Dork both have thighs, shins, feet, and toes and nothing really different up to the buttocks Mike has and Dork doesn't). Of course, if these are just regular boots, it should be noted that the Tailor only copies morphs, it doesn't fit things to other meshes or shrink-wrap. Here's another example of something you cuold do with The Tailor: load up the Dork's head in a modelling program, and load up Mike's head. Move the dork's head so it fits closely with Mike's head, then create a custom MT to make Dork's head look like Mike's. Be VERY VERY CLOSE! Like, match the skin surfaces as perfectly as possible. Export the MT without moving it back down to Dork level and then make a base conformer (zeroed-out) Mike point to it as a figureResFile. Then set the Tailor to work copying Mike's morphs over to The Dork. Just don't distribute them because that would be thin ice. But if you own both you can certainly do this for yourself to get a more expressive Dork with bigfoot features and elf ears. That's what the tailor does. It copies morphs between meshes that don't match up. Now if someone would make something like that for UVMaps I'd be ecstatic!
