When Lau Lau was studying for her art history exam, she taped all of the three hundred and some pieces up on our lounge walls in chronological order. And out of the three hundred and some pieces, sadly, art-ignorant me only recognized one: Renoir's Luncheon of the Boating Party. Try the look for yourself with straw trillbys, raffia flats, your lived-in Hanes tanks, and gauzy floral tops.

Edit: I just noticed, but doesn't this remind you of Kiera Knightley?
