Oh I'm glad you came by Angie, even tho it's late at night (!) I stared at myself in the mirror...
...And so there's distance between my shoulders and chin / shoulders and earlobes. But it's funny...
First off, I have very slopey shoulders. My chin is way above the ends of my shoulders, but where they meet my neck not so much. Doing the hand test, I think I'm average to a little short - but I have giant hands. Unusually so. I think it's from hyperthyroidism as a teenager. I like wearing turtlenecks and don't feel it's visually off, but then again the desire to be warm may colour my vision. I do also like chandelier earrings and have never noticed them hitting my shoulders, but then I have sloping shoulders.
And still collars really do me in, IMO. Maybe it's my little round head? Fills too much of the collar opening?
