Go to the Air Force Academy website (just plug Air Force Academy into your browser). Look at the column on the far right side of the page and click on Parents' Weekend. The schedule, etc. will come up. As for clothes -- it is predicted to be hot in Colorado the rest of the week -- it was 93+ in Denver today. Bring comfortable clothes -- unless your family is going out somewhere really fancy -- Colorado Springs -- like most of Colorado -- is casual. Wear jeans, tennis shoes, sandals, comfortable shorts, comfortable shirts, a hat and plenty of sunscreen -- women do not need to be in a dress or heels. Clothes on siblings, girlfriends, boyfriends, etc. can be teenage "normal" so long as it is not too revealing (low cut, see through, too short, etc. is probably not appropriate -- but it's unlikely anyone will say anything anyway). Remember that if you are the parent of a C4C they must be in uniform the entire weekend -- except in their hotel room, on a hike, at a hotel pool, etc. -- they may wear their PT gear under certain circumstances) which they will know) but in general they will need to be in uniform -- there will be upperclassmen at the hotels, in Colorado Springs, at the local tourist spots -- cadets recognize one another (by the haircuts, if nothing else) -- so you C4C will want to follow the uniform rules.
