Prada's new flagship store, which opened on Wednesday, is the talk of the town here in San Francisco. One walk-through and it's easy to see why. I went today and the lace bowler ($1,995) Eva Mendes carried at the Louvre in Paris instantly caught my eye. It looks gorgeous on the actress's arm but even more divine in person. The leather is buttery soft and the lace design is humble yet sophisticated. It's been a while since I've been smitten by a bag, but this one's got me in a tizzy.
