How do I make clothing fit my UNP Body?

[FutaL0ver]

Not sure how to start but I've messed with bodyslide 2 more than I'd like to admit. Tried opening it in outfitter, messing with the mesh and find out that what I did does nothing :\

 

Here's an example of what clothing I'm using.

 

Using an UNP HDT body with sweat skin and Dimonized UNP skin.

 

Also using mod manager, so i don't have any way of specifically moving files to my skyrim's data folder, as it doesn't exist.

 

Clothes are from Chapi from here http://www.loverslab.com/topic/18455-dadag-and-chapi-armorsdownload/?p=426801%C2%A0

I know the chapi outfits have many problems in the nifs. I tried to use the clothing converter awhile back to convert some of them and the outfits just blew up in the clothing converter and after a bit of testing I just threw the mod away and moved onto a less problematic project.
