LOL! Thank you all. My intention was to ask if anyone knew about a resouce for buttons props of a type that would fit on this garb and that can be distributed in a freebie. Maybe I hoped, someone would graciously offer to provide them.   If none such is available I will have to use my own poor skills to make buttons myself. 

I intend to add them as rigid decorated elements for the dynamc version and simply set-in-place for the conforming version. Structural or 'welded' connection, as Vilters rightly advocates will be easier with dedicated buttons but this would slow down release of the freebie. 

Marvelous Designer indeed right now has no good solution for this. The use can 'tack' imported objects to cloth or avatar but this is not a structural connection that is exported.
