• said top wall having at least a portion that extends substantially horizontally to abut to a wearer's head to maintain the headwear piece in a consistent location on a wearer'head,

• said front wall curving into laterally spaced side walls,
• said front wall, top wall, and side walls being configured to cause the appearance of the headwear piece from the front thereof to be substantially the same as that of a conventional baseball-style cap,
