While they did recycle various aspects, no one swimsuit is an exact recolor (except for Kasumi and Leifang). If you base it off the style of tops, you will notice that three girls may share the same top, but one is wearing denim shorts, another a mesh top, and another a skirt. Other than Leifang and Kasumi, no one shares the same combination of styling. With that being said, the only person who has a truly unique swimsuit is Marie Rose. She is the only one with that style top and bottom.
Also, it's funny how so many people were commending TN for the show stoppers encore pack when they were all recolors, but this pack already has people complaining about recycling parts and people are getting mad. I think this pack is excellent because they actually made an effort to do the characters justice. Some characters who normally just get lazily put together actually got truly fitting costumes, such as Lisa and Mila. I am going to enjoy both the new stage and the new costumes I have already decided. I personally think this season pass is going to be more promising than the first (though I wish the men were going to be included more than once).
