When Blizzard's Equipment Manager and Outfitter are both enabled, the buttons in the PaperDollFrame overlap. Would it be possible to detect this condition and move the OutfitterButton to the left? If detecting is difficult, just move the button to the left.
I changed line 587 in Outfitter.xml:
<AbsDimension x="-64" y="-42"/> <!-- <AbsDimension x="-28" y="-42"/> -->
