I wasn't able to find out much about this company, but this particular one was mailed to a Miss Elise in California, so they must have been nationwide. After all Florida Fashion Inc. "Brings Florida Glamour To You!"
Actually I always enjoy these sorts of catalogs because this is what women really wore and bought for their families. My mom (or your grandma) would have ordered from these exact sorts of catalogs and paid these prices. They could "Look like a Million! - for little money".
