Thank you @QuelleFromage. Considering I think your taste is stellar, your compliment means a lot!Your collection is perfection IMO. Do you want to try:
a smaller Kelly, maybe a sellier? Rouge H box or a dark blue? Or a smaller black K not in box?
a pale grey (gris T? perle), raisin/prune/or green Kelly?
a killer clutch like a Medor? I don't know how big your Halzan is but maybe you need a mini bag/evening bag? With your classic tastes I'd say a Rouge H box Medor clutch with PHW would be amazing for nights out.
I think Evelynes are always casual but I also think they are so useful and a bag where you can experiment with color.
I like your idea of a smaller Kelly. Hmmmm.....
