Apparently its National No Bra Day today (Oct 13th).

Excerpt -
Not wearing a bra is the most comfortable thing for every woman. Bra tends to be hideously uncomfortable. The bra-wearers know all about this. That is why National No Bra Day is a great excuse to throw uncomfortable feelings away and go all the way without a bra. But it is not mandatory. You can still wear a bra if you want.
Ummm, mine is VERY comfortable! Been wearing it all day and it still feels wonderful!
