We're betting they already have it. Diesel's Fall/Winter 2010 Collections of just about anything, but for our purposes, especially their 'Intimates' are being promoted by the tag-line/theme of Be Stupid (Go ahead, click the link. It would be stupid if you didn't).
Aside from hip hipsters and pretty panties, they're also hawking their shades and other eyewear, which seem to afford some degree of privacy. As private as it gets when you're stripped to your camisole and panties with balloons and candle-lit cupcakes on a subway train, anyway..
If she had just read this post before a few books from her local library, she may have felt less exposed if she'd worn shades instead of her specs.
Of course, if you're looking for better reading material..

EDIT: But wait, there's more! Attention, that is. Not sure it's the kind they wanted..
