I like the last on as well but I recommend incorporating the bias tape along the edge of the vest.
You might take inspiration from this Character design on that.
The underskirt could also be two tone with the body yellow and the sleeves and collar white.
The only thing I'm afraid of is that the dark pink might be mistaken for Kyoko Sakura. Her "red" is on the pink side of Burgandy. I thin the body should be a muted pink (you don't need it to be as bright of a pink just lighter) with the dark pink/red as accent's.
