I've pondered this a little and conclude that it's a trick question. No wonder you're getting so many answers, lol.
Women are an overall package. There's a lot more to a woman than a pair of nice legs, or boobs, or hairstyle. It all comes together to form a complete desirable or undesirable package. Even beyond the outward appearance of her body, there's something which shines out from within. Light or darkness. Some would call it aura, some character. It's the same thing.
jason tried to appease you girls and your question by giving an answer, but if the girl had nice legs, and was otherwise gross ugly, or had much darkness in her...he'd keep on walking (even assuming that he was in the market for a GF/wife.) Does she have a good heart? Love the Lord? How does she speak about herself and others?
Your question as written would be better suited to secular men and not a bunch of Christian guys, lol.
