Not sure, I look MUCH younger than I am though. I'm 21 and I look 14 or 15. Even with makeup, I can't get myself to look any older than 19. Most eye makeup bugs my eyes anyway so I stick to foundation and blush when I do wear it (which I'd say makes me look about 18).
I'm average height so it can't be my height. I think it's probably because I have a baby face rather than a young looking body.
I get talked to like a little kid a lot, by random strangers too like cashiers. I once had a lady look over my credit card (yes, some aspies do have them) for about 10 seconds and kind of hummed and hawed over it before saying "Okay then, can I see your ID?" in a "I don't believe this is yours" tone of voice. It's very rare that someone acts for an ID for credit cards here since 95% of credit cards are protected by a PIN here.
I always get carded for alcohol and I've even been kicked out of a wine bar. Once, a waitress told me I couldn't have a drink because it was alcoholic. I now just put my ID on the table if I plan to order a drink.
I can't grow a beard so that won't help.
