There are no pictures of it yet but the Return Road dress is a classic Ayu BIG dress. The bottom is big and round and lights up in the corset and the bottom round section (the entire corset lights up and lace and design throughout the bottom light up) The light changes color throughout the song. The big round section that lights up is then removed for the walk down the runway (the bottom is then the one in the photos) but the corset still lights up. I wish there was photos of this outfit!! There are only photos from the first nights dress which was not the one on the second night and which she is most likely using for the rest of the tour. Think the dress from My Story that starts off round (there is one of those right lol). The outfits for this tour are really quite stunning and the photos don't do justice imo.
And yes the only tshirt she wears is the encore outfit, which you know, shes been doing for quite a bit of time
