If I had to guess they might have special ones for the tour. As for the the red ones and beeswings ones will the same. Since it will represent with the scenery so well it's possible the director wants them to be as organic as the special. With up to 4 dress changes this will be the question and what will most effect is time in a solo needed for them to change. You can bet your dollar it will be tour versions otherwise they'll trip with the dress bottoms hanging.
I would assume the set of green dresses could make up one act, and the red dresses the other. Should there be a céilí song, I would see Tara remaining in her green dress, but the other three in the pastel-coloured dresses which appeared during
The Galway Shawl in the special
