I'm unsure about whether or not the jeans look good on you, but they sure do look tight.
I own skinny-fit jeans and whenever I put them on, I'm always overanalyzing my hips; but they're my hips. And they're there. I'm 5'7" and wear a U.S. size 4. I like my body, but as an African-American woman, I am aware of the stereotype that African-American men don't like women who are on slender side.
But more important than race, I think culture has more of an impact on preferences. Today, many races and cultures are being affected by MTV and the like, so sub-cultural preferences may change unless they are preserved. Growing up within my immediate family, "American culture" was the standard, growing up with things that were nationally recognized as the norm, without many sub-cultural influences.
