You know, seriously....I think a lot of it does come down to acknowledging your true physical appearance, and dressing for it accordingly.
For instance, look at this pic of Queen Latifa below...
She's a big woman, knows it, and thinks she's gorgeous.
I think on the whole, black woman are much more comfy with their bodies.
To me, when I see a black woman really dolled up, she looks regal.
Now a white woman might look just as good, but just, I don't know, doesn't pull it off with the same level of comfort.
