Export items from D/S using the Poser settings to start with, no textures included and if you do not want pieces, then unselect "groups". When exporting the clothing then out of Hexagon, use the 1 m setting. When importing that into D/S [Poser settings] it should be landing in place on the figure.

If you import ANYTHING into Hexagon and it's miles above the grid, delete that, and try importing using the Poser setting which would be 0.41 percent of 1cm. Note though that you can resize and re-position the CLOTHING item to fit where you want on the figure [i.e. V6] which of course must NOT be moved. [can freeze it with the scene tree options].
