I think this hairstyle is very cute and sweet, and I'm a bit surprised that it's by Newsea since it looks more Skysims-esque. A big thanks to brookedanielle93 for donating all three items along with a ton of others. Feel free to add her on thesims3.com by the same username or check out her blog here (at least say thank you to her, she has been very kind and helpful). This is for females only; toddler to adult.
