"Party Attire"?

I don't know this stuff AT ALL.





I'm going to a Bar Mitzvah tomorrow and the invitation says "Party Attire." I have absolutely no idea what that means. The party's at Dave %26amp; Buster's. I'm planning to just where a dress shirt and the pants from my suit.

pants from a suit are not really good to go with a dress shirt. You will look disheveled. And if you don't know much about fashion, I think they are pleated. Go to Gap, or Banana republic and buy a pair of flat front gray pants. Get a Blue pin-stripe shirt that fits! by fit, I mean the shoulder seam is not droopy, and you cannot pull much fabric away from you. The pants should just touch the ground, and the waist should fall at or just below your belly button. Your shoes should be black, no square toe, or scuffed shoes. You belt should also be black, but brown is ok.
"Party Attire"?
I agree with the guy above me, but with maybe with less detail.
