I do not own both, but I had the opportunity to try them at the boutique twice. Prior to seeing them in person, I love how the Passy looks because I felt it would be functional, lightweight with the leather shoulder strap, and I felt the large LV logo is something different from other bags released from the fashion house. Merely looking at the pics, I felt the Victoire would be too dressy yet abit dated.
After seeing and trying both in person, I no longer have any interest in the Passy, unfortunately. The Victoire is much more sturdy and well made, overall. That bag definitely elevates any attire, unlike the Passy. I think that the Passy's canvas would curve in a matter time, and I did not like the large gap at the sides of the flap. I would spend a couple more on the Victoire because it is really beautiful, with both chains on the shoulders or crossbody. I believe the advantages that Passy has over the Victoire would be the back pocket, and it is more lightweight?
