It is NOT strictly mandatory, but good practice, to parent the cloth to the hip.

But as said before?
Did you start from the standard "T" pose"?

At the start of a sim, NO intersection between the cloth and the posed figure is alowed.
The cloth object may NOT touch the "to be clothed figure".
The arms have to be inside the sleeves but not touching them.

Did you check and fill the collide against box?

So many questions??? Possibilities???
