But costumes are NOT for women only! One man -- part of a cheerleading squad! -- wore a kilt, fishnet stockings, and high heels.

Another couple (below) dressed as ... well, we don't know what they were dressed as. Any guesses?

Some protesters made the effort to dress up, but other costumes were a decidedly low-budget affair. One woman arrived in full pirate regalia (or is it a Founding Father?).

But another woman sported only a cheap wash-off tattoo. (You just know her grammar school science projects included an exploding volcano and clay model of the solar system.)

Buying a costume is risky, because you may not be the only one showing up in it.

This woman wore a smart-looking flag cape that critiqued corporate America. Svelte and colorful, with a hint of class.

But alas, she was not alone! Other protesters were spotted wearing the exact same cape!

Fashion faux pas indeed!

And this protest had 'em!

Floats included a giant pig representing the GOP's policy of fat corporate profits ...

... and a giant penis representing, well, once again, we're stumped as to what it was supposed to represent.

Even so, the giant penis was a popular draw, attracting many cheers!

Displays were also popular. One man brought an original Florida 2000 voting booth, carrying and re-setting it every few blocks. (It was an article of faith among many protesters that Bush lost and stole the 2000 election, a theme of many signs.)

Another woman delighted folks with her Condi Rice head.

Of course, it's not a protest without music -- and this was no exception!

Street musicians peppered the protest route, lending their talents to the delight of one and all.

A protest is like a parade -- and everyone loves a parade!

With so many costumes, floats, musicians, and displays to see and hear, it was no wonder that people watched and cheered from windows, fire escapes, and rooftops!

Others did more than watch. They joined the spirit of the event by unfurling their own protest signs!
