I suppose if I had to choose, I would pick my hair because I’ve always liked the color and texture. I am the only one in my whole family to get the dark brown almost black color, and it sets me apart from my sisters (who are gorgeous in every way possible). Plus, hairstylists usually compliment me on my hair, so I always thought that was a positive thing.
I’m not sure that counts as a physical feature, but I think it should suffice since I’m having a particularly hard day and can’t seem to think of anything else noteworthy about my body.
