When did “cocktail attire” mean 7 jeans? Jeans with a lingerie tank top is NOT the new LBD. Middle aged women with saggy arms and paunchy stomachs wearing tight jeans and lacy camisoles to cocktail parties and formal dinners make me want to gag. The OC has inspired mothers around the country to dress like their 15-year-olds, and it is not a pretty sight.
