Body not showing under transparent dress from MD

I used the 'Opacity' slider under the Property Editor/Material tab after making my dress in Marvelous Designer and chose an opacity of around 54, I saved with the correct settings and imported into Blender but the Nude top and Nude bottom weren't showing under the dress
 How can I get it to show and/or did I take the wrong steps?

(Move if this isn't the right place to post this )



Edit: After selecting the dress using the 'A' key on my keyboard the body shows underneath?
