My character's left hand is bigger than the right and when I wear clothes the arms shows a disturbing gap.

So I reinstalled the game updated it to 1.7 with no mods and it's still the same.

Is there any way to fix this?

I tried using pipboy readius mod to remove the pipboy and body mods to fix it but no luck. When I crouch and move, the left hand animation is wobbly.

pictures? My guess is it is just the FOW. Ive had reports ot the left hand being bigger with my pipboy glove remover, but found that it actually wasn't. My money is this is the same in your case.

Hello this is the screenshot.

Look at the wrist and the size of the thumb. The whole arm is longer.

No mods, just 1.7 patch, latest fose, latest fomm and a fresh install.

They are a little bias towards the left side, which would account for the FOW effecting the proportions.
