Rule one: bad content is bad. 

Clothing should always be made on the base figure. It is not DAZ 3D's responsibility to ensure the quality of clothing anywhere but as sold at DAZ 3D, or to make clothing built wrong magically work in a way not intended. 

 

Note even in the case where it isn't done correctly, you can still convert it.

 

I have not yet transferred the morphs from the original clothing to the new clothing or done any clean up, but this is Redviper's Sleeveless Tennis set on V5.
