APC 2012 May NYC (dresscode?)

[josephinbrooklyn]

I am attending the APC this Friday in NYC. Anyone else going?

Also: does anyone have thoughts on what "business casual" means? It's going to be about 70 degrees on Friday - do you think I can get away with a polo or do I have to go the button-down route?

last month when i went to beijing apc, i wear formal without tie.
but i do meet some people wearing more casual, one even wear a track bottom!
