Something that has been low-key bugging me for a long time was that some of the doll clothes in my collection were dirty.
I am really careful with my doll clothes. However, for example, my Felicity's meet dress is 28 years old, and I kept her in that dress most of the time, so it was just grubby from handling, even though I kept an apron over it.
I buy a lot of doll clothes used, and some of them came with spots on them.
However, when I was little, I washed my Barbie doll clothes in the sink, and some of them shrank beyond use. I really didn't want to repeat that.
