I agree with plainjane. Once my husband and I were in the food court at a mall. As we sat down at the counter to eat our lunch, three young women came over and sat down very close to us. One of them had on low cut jeans and was wearing a thong. She actually pulled her jeans down much lower and asked the other two if her thong was showing enough while she was sitting. Talk about making one lose their appetite. My husband just shook his head in disgust. I bit my tongue to make sure I didn't make a comment about it. I can't think of a situation where being classy isn't the correct choice.
