Thank you so much !!! I'm going today to try both in person ! I loooove the look of the clutch, it's so gorgeousI have both and love them both. In terms of looks I like the caissa clutch better. But the caissa clutch holds significantly less than the pm in my opinion, and if you put too much in it, it feels very heavy on the shoulder. So what I recommend would depend on what you're planning to use it for. Pm would be a more versatile everyday bag while the caissa would be great for weekends or casual nights out.
