When the heat hits San Francisco -- as it did yesterday, and how --two of our favorite street styles appear.

One, the woman wearing a sun dress. She looks uncomfortable, and sort of stunned, about her unusual level of public nakedness.

It makes sense. We too own sun dresses that sit in our closet, waiting for the one hot day in San Francisco to come out. Yet when that day comes? We just can't stand that much physical exposure, that much skin revealed. So, we leave it in the closet and wear our normal clothes. which are way to toasty to wear on warm days.

Which then leads to our absolute favorite SF hot day style: the rolled-up jean. Look in any park lawn or on any quarter-sized tuft of grass and you'll see people lying around with their jeans rolled up into shorts and their tops bunched up into half shirts. Those of us who come from a places with actual summers deem this look "The San Francisco Bikini." Some think it's dumb, because: why don't they just by shorts?

But we think that latter is a style we SFers should wear proudly. It's the spontaneous expression of people who feel summer heat so rarely that they'll bunch up their clothes and plop down on bum piss covered grass just to get a piece of it. That kind of gumption should only be admired.
