Issue with skin

[greenmoose]

First off, I'm not entirely sure if this is the right place to post it, not even sure whether anyone else has this problem.

In short, my skin is completely broken. This issue does not happen in vanilla minecraft, it works fine on other modpacks, but for whatever reason Tekkit Lite doesn't like me. I have reinstalled tekkit lite, I have reinstalled the launcher, I have reset my skin, this worked (the skin was normal) but when I put ANY skin back, it seems to break.

Essentially, my torso part is where my face should be, parts of my body are black and my arm is currently found in the torso. 

Literally any help on this would be appreciated, thanks
