Couple of things:

Pirates of the Spanish Main is a thing again. (Also, It’s a pain to take the ships apart after every game. Just get a bigger box.)

I love the button game. There’s a couple other games with the “Feel through the bag” mechanism, namely Dr. Shark and Space Cadets, but this sounds distinct enough. I would like to put my personal vote in for anthro animals if that swings things at all.

I don’t see why specific buttons would be hard to find. Way more people wear clothes than play boardgames, I should think that buttons would be a pretty easy thing to find a wholesale or manufacturing company for.

On that note, would it maybe work well to have the button requirements relate to shape, size and texture, and have each player have a bag of buttons in their own colour? It would make it more obvious who was working on which customer’s suit.
