I’m also thinking of adding a shoulder strap! Would love to see photos.I actually made my first LV purchase one day after you, 4 March! IMO the split at the cardholder definitely doesn't look normal and in long term the tear is definitely going to enlarge. I don't see this for both the Felicie I'm holding.
I'm thinking of getting a shoulder strap too! Mind to share how the 16mm Ebene shoulder strap looks tgt with your Felicie? TIA!
