It's International Wear-A-Dress Day 2008!
Although, really, to give people more of a chance to participate (and as long as we're creating our own occasions) why don't we call it "International Wear-A-Dress WEEK 2008"?
I made a Flickr group for people to upload photos to, it's , and I'll try to post great examples next week if people upload them, hint hint. (If you don't want your dress blogged, please tag it DNB — for DO NOT BLOG — when you upload your picture).
I will most likely be wearing this dress.
