Her clothing is beyond words. For age and style it doesn't surprise me. Smiley faces were popular when I was a teen in the early 70's so that makes it about 50 years old. I will say this, I wouldn't be caught with any of this then or now.
It's hard to believe that she wanted this stupid symbol on her clothing. While I don't generally care for her styles, I do think she has exceptional color sense and her prints are often lovely. However, this is simply cartoonish and embarassing.
