I just received my Nora today! Other owners told me 5/6 wigs which seems to be perfect; She's a bit taller than other yo-sd and slim, I don't have any myself to test this but others told me she fits TTYA clothes perfectly. I would guess her eye size is 8mm-10mm, super teeny! She fits into smaller yo-sd shoes that my chunkier yos can't.
Thank you I just got back into the hobby after nearly 10 years and have nothing for dolls anymore. I never bought 8mm eyes before so gosh, that really is tiny
