Top 5:
Consideration/decency. Most guys (and gals for that matter) can be an angel to someone they want/want something out of. I like to look carefully and see how he treats everybody - is he respectful? Is he helpful? Is he caring? If I see someone doing kind deeds for others this impresses me.
Confidence
Humour, wit in particular is something that generates chemistry for me and is very important. I like that cheeky/flirty sense of fun.
Respect for my independance and individuality.
I find loyalty/admiration attractive, I am a bit of a sucker for devotion (need to feel loved?). But not the desperate and often rather selfish kind. The kind where I feel someone really knows me, and likes me for me.

There's too many more to list really, I don't especially care about hair or eyes or any body part or even height in particular. I'm very short so it would take an exceptional guy to be shorter, even then I wouldn't rule it out. I like an attractive face but my range is pretty wide (I tend to start fancying people I was initially put off by), I prefer a slim athletic build but again I'm pretty tolerant. I don't really need someone to be particularly intelligent (although a certain kind is required for wit), or ambitious - I have enough of those of my own; provided they aren't really lazy/a waster. Honesty is fairly important, but tbh it's not a special priority of mine - I think "loyalty" covers the important stuff. I quite like someone up for a discussion.
