[SOLVED] How do you make a part be orientated in relation to your torso?

local offset = Vector3.new(2, -(1.6 * head.Size.Y), -13)
newEffect.CFrame = head.CFrame * CFrame.new(offset)
newEffect.Orientation = Vector3.new(0, head.Orientation.Y - 90, 90)

I've done that, however it only works when the player is standing up. So if they've fallen over and are facing the sky, the part will not be orientated correctly.

I've tried fiddling around with look/up/rightVector but I couldn't get what I wanted with those.

Note: The X or Z values of the orientation have to be 90 or -90, otherwise the mesh inside of the part will be orientated wrong.

Pictures for slightly better understanding:

EDIT: Solved it! Completely forgot about radians. Removed the orientation line and added onto the cframe line.

newEffect.CFrame = head.CFrame * CFrame.new(offset) * CFrame.fromEulerAnglesXYZ(math.rad(-90), 0, 0)
