I'm not sure if anyone noticed but C1 Marie Rose's bloomers are different from the 5UA's trailer.
Her bloomers on the 5UA trailer are just plain white while here on the location test trailer, her bloomers are white with small red prints (probably polka dots or strawberries). Does this means she gets alternate bloomers? Pai in her maid outfit should have the same function as well.
It's very likely, in the end the bloomers are her underwear for that outfit (same with Pai) and we already know like TN make possible alternate version of them for all the girls that have an outfit showing it.
And If Team Ninja will decide to create at least an original swuimsuit for Marie Rose, like an user of Doaworld posted, I'm sure that she will take this classical chihè swuimsuit XD
Returning to the gameplay, I really like what I see. The character seems to be unique for the DoA roster not only in her appearence but also in the gameplay that in the end is the most important thing (in addition I don't play Tekken, so for me there aren't similarities that I can led to the characters of that series).
I also like how the character seems to be pretty technical on the chart for the Doa canons, and apparently even really competitive against the other, just like all the other DoA5U addition (maybe with the only exception of Ein

) were revealed to be.
