Different modelers , different modeling software and different figures equal somewhat different levels of quality on a standard use conversion.   There are a whole toolbox worth of conversion tools in Wardrobe WIzard to attempt to accomadate  the varibles in the creation of the clothes.

Most of the time, standard conversions do the job, but given the variables--it's a bloody miracle it works at all! LOL   Don't give up  and keep at it.  ^__^ V,,
