Jambette probably, those lips just... no. Gigi and Diva are kinda weird too but at least their appearances fit their personalities somewhat.
I think Cousteau is cute. Usually I find mustaches awkward on villagers but his fits him. One of my friends had him in their town and he was really nice.
Diva is nightmare fuel and I have her in my town, pretty tragic really. I also don't understand her hair, looks like sloppy sideburns with terrible bedhead. Also don't get me started on her horrendous makeup, I could go on.
