They're khakis, the color is washed out in the photo. Is that still a fashion faux pas? I rarely pay attention to these things. It was a comfortable pairing. The khakis were lighter than jeans so I wouldn't get overheated walking around the park, but not shorts so the A/C inside attractions wouldn't freeze me.
The strict rule is that all khakis are now reserved for 8th graders going to a school dance, but that only applies to if you're going out on a date or something. Jeans are the in thing right now. There are tons of different jeans styles now. For more formal events it's slacks.
I still wear khakis to church, to work, on a quest for the Holy Grail, or to Thanksgiving dinner or something... I still like khaki cargo shorts.
