Sveta, I am just so impressed at your narrowed down but utterly perfect shoe collection. Each piece fits your style to a T!
I see you already have some strategies nailed down from the catalogue. I could see another pair of flats, tall boots, or short booties, working well in your collection as you se to have a pretty robust pump collection already.

Before I read the other comments and your own thoughts, my first instinct was adding a dark tall boot (black, burgundy, gunmetal) and a patterned or metallic boogie would be a fun addition to your footwear wardrobe.

Sveta, I have no advice aside from what has been offered but I admire your persistence and dedication and will be watching from the sidelines and cheering you on. Next year I hope to GO to the NAS sale with you. I am missing it all again this year!
