Daz Trouble fitting clothing made in Blender

I would like to model clothing in Blender and import it into Daz Studio and make it auto fit to daz model. I tried exporting such obj’s into daz but daz does not want to save them as fugures. What methods do daz market place vendors use to make clothing that conforms to daz fugures?
If anyone here knows a bit about daz, I’d like to know your suggestions.
Thank you.
