You said "hot chicks" so I assume you meant physical appearance as well.
In that case, I like them short (5'7" max, preferably closer to 5'0" though) and petite. They also have to be young looking, but the petite girls usually are. These girls should have the "natural" beauty and not need much or any make-up. I like the cute, schoolgirl, "girl-next-door" type. I like most hot chicks but my tastes differ a lot from others, and I often find myself liking girls a lot of guys don't really like as much, which can be good. Their weight should be somewhere within the normal range for their height. Body shape should be the "hourglass," but as long as they have a nice ass and big hips I am happy. I like nice thighs and legs too. Feet should be rather small, not man feet, lol. Ideal ti-t size is B, maybe C, nothing too big.
Ideal hair/eye color: light brown/green... All hair and eye colors are fine.
Their clothes: not picky but I love capri pants, short skirts, tight jeans, sandals, and other preppy girl clothing.
She doesn't have to be perfect like this but these are just the things I generally like. I consider myself VERY picky. I see guys dating girls everyone likes all the time that I would not even be physically attracted to.
Oh yeah, an accent of some sort can be sexy, such as a southern accent.
Personality: I am not at all picky here, as long as they're not a bit-ch, slu-t, snob, or attention-wh-ore. I like a girl who acts feminine, plain and simple. She should be submissive, decent confidence, somewhat intelligent, loyal, laid-back, mature and down-to-earth, non-slu-tty, and most importantly of all, very nice and caring. I could care less about: her social status or skills, how funny she is, and for the most part how confident she is. If I am physically attracted to her and is not a bit-ch, she's pretty much fine with me, because for excitement and fun, I'll provide the rest
After all, I am the man.
