IMO too big bc I find a 28 cumbersome if I am carrying a drink; a bite; and meeting and chatting. But it’s whatever you ware comfortable with. If you are close to the hostess, you can leave the 28K in her room if it gets in the way
I’m fond of clutches bc they can slide under my arm or lap. i used to think a wallet used as a clutch was horrendous, but these days i quite like a kelly longue wallet worn as a clutch. . .
ETA: its only early Nov. Is it possible thst you might stumble upon a suitable clutch while shopping between now and then?
