I received those glasses as a gift two years ago, and honestly, I'm not too fond of them. They are more of a mixture of a light and dark pink than a purple. I am also not a fan of the shape; they look too round and too big, IMO. They are rather young-looking, but then again, all of my dolls are 14. I used the glasses in a flashback photostory. I'm actually considering selling them because they really don't get a lot of use.
I had them and I didn't like them either. Not only do they not look good, but they break very easily...the arm of one of the glasses came loose within a week and I can no longer use them. I bought the brown ones thinking that they would look better during CM, but I still wasn't fond of that look and I sold them.
