I'm not so sure it's the look (though there is a possible butt size correlation I'll get to at the end of my post) but rather more so the mannerisms of some chicks. If I see a chick waste no time taking a look at hands, feet or crouch then I suspect I may be in the presence of a size queen. That alone isn't enough to label her a size queen though, as many women prefer extra but aren't size queens about it. So I would need to see how much time she spends on crouch watching before I strongly suspected size queen. If I see a chick only looking at my face and not even taking hardly a glance at my body then I suspect someone who doesn't really care about size. From what I've been told and from my experiences around them I also believe that black women in general tend to put more emphasis on size. I clearly see black chicks checking out my hands, feet, and crouch more often than I do white chicks, and from reading around forums I've also clearly noticed that the mostly white chicks at IVillage speak of lower ideal penis sizes than the black chicks at BET do. There was a study done that showed a correlation between the size of men's butts and penis size - the bigger the butt naturally was the greater chance there was he had a big dick. Of course it's no absolute, as a flat butt guy can have a big dick and a big butt guy can have a small dick, but correlation wise there is an increased chance. Even though the study pertained to guys I think it could possibly apply to gals also. If so, then a gal that has a naturally bigger butt may more often have a natural tendency towards bigger dicks since she has an increased chance of being able to handle more.
