So, my cousin's wedding is in late May, and the theme colour is blue. OK, I can do blue:
Vintage blue chiffon dress I bought years ago at a yard sale, and which makes me look as though I should be gesturing emphatically at the new washing machine for 1959:

Bolero-size cardigan knitted this week from some sort of mystery yarn, probably an acrylic-mohair blend.

Satin floral hairclip that I should probably wear instead of the waterlily. Purchased last week at Bazaar of the Bizarre:

Orange straw purse from Goodwill:

Not shown: purple Rocket Dog pumps.
