Moonlight Falls for sure. Pretty Sims - Fawn Goodfellow, Sophie Rogers, Emelie Van Gould, Mara Nix, and even Bailey Swain (hate to admit it) are quite pretty. In the homeless townie department - Titania and Oberon Summerdream, as well as Carmella Hai. And if you get rid of the nose, Hetal Anjali is actually quite cute.
EDIT: Frida Goth of the Goth Ghosts is actually very pretty although she had a weirdish nose, as is Violet Slymer if you tone down her nostril sliders. The Durwood kids, Faith and Felicity MacDuff, Marigold Maldano (she had weird lips but other than that is gorgeous), Miriam Hoppcraft, Janet Pok, and Alice Fitzgerald are some of my other favorites.
