I generally go with jeans or slacks and a polo or collared shirt. Nice socks, dress shoes. And ladies, what do you prefer?

I personally do not have a preference as long as a guy looks presentable.  I say just wear what is comfortable.

I like a gent to dress in whatever way best accentuates his personal style. Suit & tie, jeans & sweater, artists' black, leather biker jacket & boots... and of course I love to indulge in playing dress-up

Whatever fits your taste, no one can tell you what you like

Re:

Do the girls prefer when guys wear cologne?

Some have a preference on what we wear, it is always sexy without a doubt........

more then just a speedo, better then old ripped up paint covered overall's, and less then a tux.

Honestly you will want to wear what will not draw attention to yourself...  However if you want to dress to turn me on, I love a crisp white button down, black slacks and the clincher classy suspenders!  OMG that makes me want to drop to my knee's the min you walk in the door.  Such an incredible turn on.  However I still say dress so that you are not drawing attention to yourself or the lady in the room, that makes for the best of times!

If I come to see you dressed like that, and you burst out laughing...

Well... just don't
