I have a K25 and consider it a daytime bag.
If I want a clutch, I use my BBK longue wallet as a clutch. It fits my iPhone and cards, and antibacterial wipes. mainly bc I already own it and bc at 17 ounces empty, it’s too heavy for a wallet. If I want more capacity, I have a medor 29. I also have a flat silver chèvre clutch by Hermes in a discontinued style in case I want something metallic. And I also have a vintage matte croc chaine d’ancre bag that can act as a clutch. But, I’m not really a fancy black tie person (which in my mind calls for a fancy minaudiere or satin clutch). I have occasionally been tempted by a satin BV stretch knot. But never got around to buying one.
I go back and forth re the merits of a mini K. My SA thinks that in the right combo, it might work for me, but I think that on a person over average build, it can look like a toy bag.
