Oh come on... you already know the answer to that one :)
haha but really, every polish person I seem to ask, they manage to tell me that I really don't look that polish! If anything, I have a more defined jaw line, a 'polish nose,' and a thin upper lip (which someone mentioned at some point) but beyond that, I'm not so sure. I've never randomly gotten asked if I'm from a different region/country/etc, and it's not as though I live in an area with a tremendous amount of variety/mixture like New York haha. My body type would fall under what some people described earlier as well, but I'm more so interested about facial features.
However, we did decide at some point that you can tell many poles apart from their eyes and that mine could be classified as polish (....whatever that might manage to mean), but I feel as though it's just another one of those things that you really can't define. I'll say it again, but some people just have that automatically polish look!
