This is stunning. I think you could wear it like this, matched to shoes, in a classic manner. But, it could also substitute for a black or other neutral bag, in other words, worn with anything, white sneakers. Navy, beige, taupe. . .
Rouge sellier against an all navy outfit with black shoes (for a more fashion, less sartorial look)
RS against a navy sweater and white pants, white sneakers (RS like a pop of color for a sporty look )
RS against beige or taupe shorts, white, navy, black t shirt (RS with white sneakers or dark or light neutral chypres
to make it casual

Or with anything earth toned, like olive cargos etc etc, converse sneakers or vans to take it down a notch, if people still wear those. . , I think a 28K worn short crossbody strap on the back is a very sporty look too. And, over a t shirt or some such, it won’t ruin clothing.
