This has been an interesting thread to read!
My best friend collects BJD's and she doesn't care what people think! She takes her dolls to work so that she can sew or knit when they not busy and she takes them on holiday. She is always making clothes for them . I have never seen anyone react negatively. People are generally curious and fascinated; especially with the detail on the dolls.
I on the other hand collect Barbies (I also have Moxie Teenz and one H4H girl). There seems to be a completely different response to these! Usually it's met with 'you're an adult, why you still playing with dolls?' People aren't curious, they are freaked out by my hobby. So I feel very uncomfortable taking them out, even though I want to. Besides, if I take a doll with me anywhere it freaks my husband out. It's bad enough I play with dolls at home! (In his opinion)
I wish I could just ignore what other people think and say, but I don't know how to do that.
