It's rare to find archival images of "ardent," female polo enthusiasts. I don't know much about this historic match but I do admire the lady player's classic causal sporting garb.
My favorite ensembles: slouchy cotton pullovers, soft collared polo shirts, wide flared jodphurs, boots and wide leather ring belts. Pony as low maintenance, offscreen accessory.
It's striking to see match action w/out corporate tents and fashionable onlookers in the background.
