Child-like style can be colorful and fun. While not crazy about high-waist shorts, I do like those tan or mud shorts on the model in the first picture of Post #382. From the same post, there's nothing like girly, cute innocence. That's what the lovely dress in the second picture is. Lovely dress! The third picture offers an... okay look. "Okay" also describes the fourth picture's dress.
If anything, I think the first picture is probably my best definition of child-like style with a varying array of colors to form one complete look.
