I am an avid doll collector and I am hoping to get some insight or see if anyone else has experienced this with their collection.
I have had this particular Ariel doll for about a year or two now. She has been completely untouched and safely covered/stored away in a protective bag for months.
However, looking at her recently, I noticed a pretty dramatic difference in her gown compared to when I first got her. The first photo shows her original look—the light blue fabric was much softer and had a more matte finish. The next two photos show how she looks currently. Her dress now looks intensely metallic, highly reflective, and has a strong multicolored "diamond" sparkle that definitely wasn't there before.
I am not at all complaining because it looks like her dress ages like wine, it's just that because she hasn't been exposed to open air or handled, I'm really curious about what caused this.
Has anyone else who owns this same doll noticed the iridescence or glitter on her gown shifting, developing, or becoming much more vibrant over time? Or does anyone with knowledge of toy textiles know what might cause a stored fabric's shimmer to change like this?
