Generally I'm all about seeing her ass under her skirt, or in her jeans. BUT if she's got nice looking knockers then there's what I will be looking at first, before my eyes scan quickly toward her ass, then her lips/hair/eyes.
I love women with really long lustrous hair - wavy is awesome, and the eyes, and the lips, with the round spankable ass, and gorgeous bouncing busoms - if there's anything like an hourglass there, my jaw is dropping open.
