Nice isn't about physical appearance, its about personality. They will always go out of their way to help others. Someone who is "nice" demonstrates respect, compassion, & integrity. They are considerate, but not meek. They are sweet, but not fake. They are honest, but not harsh. They care.
I chose this outfit because this outfit represents me and actually looks almost like a replica of me. The reason I chose this appearance for my model is because I try to go out of my way to be nice to others and help them, I feel that I respect their opinions and I am honest but not in a mean way. I'm not saying I'm perfect, or nice all the time even, but to me, this is what represents nice: a smile. I feel that this outfit embodies niceness, but of course it is up to interpretation.
