When I was around 15 or 16, I was always told that I could pass for 21. Now, I'm 25, and I'm regularly told that I don't look a day older than 17. I was sitting in a doctors office the other day, and the nurse told me that she felt the need to double check my chart several times, as she felt there was no way that I was over 17. I asked her why, she commented that I just look so young. That sort of thing happens regularly.
I'm 27 and still get carded sometimes for things I've been able to buy for years. Less so in club settings because I have boobs, but at stores I tend to have to get my ID out a lot. I think this has something to do with good skincare and genes and a lot to do with how I dress. If I was in my work suit, I never got asked for my ID. In my regular clothes it's almost inevitable. I also get asked a lot about if I'm married when they see me with my son because I look "too young to be married with a kid." I've been married for five years and my son is three. O.o
