There was an old method the figure creator mentioned several times in the past:  

Do not conform after loading in zero position.  

Pose Apollo, then copy Apollo's pose to the clothing.  The scaling poses would also be copied, if the clothes were design for Apollo.  

You're at the mercy of the Fates, if otherwise.  I have had a terrible time with converted clothing from other figures.  The upper arms could never be correctly converted.
