I guess it it the same as for heads:
I have my basic head mod loaded through $INIT folder.
Just install the head you want in the $INIT folder.
I can't really tell more, as I don't use the Loader, except for my example screenshots...
What I can tell is that "clothes" for Him doesn't exist as such. Only "bodies" are available (e.g. you can have a body wearing a tuxedo, but there is no tuxedo mod to add on top of His body, because it's only one image, not like Her body on which one can add clothes, accessories, hairstyles, etc.)
Look in
HIS Body category.
