Oh, hm.. maybe I have some problems with translation. Do you mean the buttons? Because with grouping tool you could make a prop from an existing button on the suits and just put it into the right place. ...

... and while I am typing my brain was telling me, maybe you don't want the jacket open, you need it closed.. or?

I am sorry, but I will remember you whenever I see a suit.. and I tell it here :D :D ... Really sad that the Poser males have not that much clothing unless you will put them into nice dresses or bikinis XD lol
