At Blind Brook Polo Field in Purchase, N.Y. a race meet brings out one of autumn's most fashionable crowds and shows the look of fall and field in many facets. It reveals a preference by men for bold plaids and checks, for shawl-collared coats, for vests that match suits and contrast with sport jackets. Solid-color blazers and jackets are set off by checked trousers. Hats have an English turn, a new high roll in back. For the ladies, there are a raft of reversible coats and skirts, as good-looking as they are versatile.
