Help with Layered Clothing

[HorrorTM (Horror)]

I’m having some trouble with rigging layered clothing onto a 1.0 character.

I’ve been following midnightkrystal’s references - 1.0 [Blocky] Layered Clothing - Resources

I’m entirely new to layered clothing and i’m attempting to learn it for use in a game i’m working on.
in blender, everything’s rigged and weighted accordingly, but i’m also unsure what to do for the outer cage. I’ve looked up a couple resources but I can’t really find anything in relation to doing 1.0 cages. do I just “box” around the clothing and call it an outter cage? i’ve got no clue.

Upon importing into studio, and setting it up accordingly, it turns out like this.

any feedback would be much appreciated, and thank you for your time.

an update to this problem, it appeared to be something in the game causing the issue, but the result for some reason still looks pretty messed up. only the chest and hip is correctly attached. anyone know why? how can i fix this?
