I wasn't sure if these were needed - but here are the instructions for changing the dress in Daz Studio so that it will work in Poser. - Not the right forum but it might help I suppose.

Open Daz Studio

• Load Genesis 2 Female
• Load the dress – then on the Parameters Tab select the dress from the drop down list.

Now open the Tool Settings tab – if you can’t see it do the following -

• Select - Window - from the top tool bar - Select Panes (tab) > Select Tool Settings – and left click on the tab when its loaded.
• At the top of the panel there is a drop down list next to Active Tool – Select > Geometry Editor. Don’t do anything with it..

Make sure the dress is still selected and Right mouse click in the viewport -

• On the drop down list choose – Geometry Selection > Select by > Face Groups > rhand
• Right click for a second time in the viewport
• On the drop down list choose – Geometry Assignment > Assign to Face Groups > rForeArm

Now choose the Node selection tool – from either the toolbar above the viewport or from the Drop down list on the Tool Settings Tab – this just makes sure the Geometry Editor is closed.

On the Parameters Tab select Genesis 2 Female

• On the Menu Tab select > File > Save As > Wearable(s) Preset
• Choose where to save the dress – Give the file a new name – click Save
• The Wearable(s) Preset Save Options Box will open – click Accept
