Yuuuup Marco will be a moron and insist he eats like a bird so he will be fine. Feel free to kick his ass with haki (Sanji's updated that far right?) or even just a stern ">:| You are worrying your nakama and that is bad for them" will snap him out of it.

As for Fujiko, she will just ask if this is good. Can Sanji even function with her wearing this?
