Q.
I used a Tango applier on my mesh body, but it is showing wrong?
A.
The usual sign of this is the texture is rotated 90° on your upper torso
This is caused by the merchant using a PARTIAL texture, not the full upper body SLUV texture.
Sadly there is nothing that can be done, apart from contacting the merchant to *politely* ask if they would consider re-doing the applier to use the full upper body template.
