I like the implications of shirt genetics between the grandmas and the mother. But I'll need to whip out a punnett square to understand what combines with black "metal 💀" to result in plain white with frills.
The granddaughter is still a kid developing her taste. It is actually a nice touch because this implies the daughter wasn't raised to like metal and chose the music as the one she liked herself (ofc with her parents' influence) and now also doesn't push her own daughter into a direction while she is still a child.
That was my read of the white shirt and it's nice to see that someone else noticed the shirt progression.
