Over the last six months, there has been a precipitous increase in the number of young Japanese women wearing giant, thick-rimmed glasses with no lenses. These are somewhere between your garden-variety, Woody Allen ironic hipster glasses and toy spectacles worn by kindergartners in school plays.
Well, I approve. Note that the Harajuku girl above is also sporting a set of steampunkish goggles, for maximum cute-age. More on the trend's origins, which may have roots in Taiwan or Korea, on neojaponisme.com. The post includes links to lots more photos of "no frames girls" like this one.
