I'm trying to import a garment from Marvellous Designer and it comes in completely tattered.

I downloaded the clothing from their marketplace. https://www.marvelousdesigner.com/store/detail/9a5897ffa80b41ef9f262438c44c27d4 
I imported my CC3 model ok into MD and applied the clothing, with it all looking fine.
When adding the garment I do get this message (I don't know if it is relevant to this issue, as it happens to other garments from the marketplace that don't have this error)


 I fit it to my character ok



I export the clothing as an object and load it into CC3 and this is what I get



the dress has been eaten by mothballs :( 
importing into Blender seems fine. Can anybody assist with this? It would be greatly appreciated. Also is there a better workflow that anyone knows when working with MD?

Thanks.
Sal.
