Frank Olive Private Collection Black Wool Hat with Looped 。Frank Olive (1929-1995) was an American milliner known for his high-quality, whimsical, and sophisticated hat designs from the 1950s through the 1990s. His hats were collected by the wealthy and were favorites of attendees at the Kentucky Derby. The hats often featured clean lines and simple details made from high-quality materials. The \"From My Private Collection Frank Olive\" label was one of his most expensive lines, indicating that the hats were often one-of-a-kind designs. After his death in 1995, Gabriel Amar took over the Frank Olive label. The hat shown in the image appears to be a vintage piece from the Frank Olive \"Private Collection\" line Kentucky derby, tea parties, red hat society, holiday avantgarde, mob wife, christmas, office party, church, Frank Olive was a well-known NYC milliner (especially big from the 1950s–1990s), and when it came to felt hats for women, he typically used luxury fur felts, most commonly: ✨ Rabbit fur felt ✨ Beaver-blend fur felt ✨ Velour felt (a type of fur felt with a plush finish) He did use wool felt sometimes, but his reputation—and higher-end pieces—were primarily fur-felt because it shapes beautifully and holds structure without getting fuzzy or floppy. So if you\'re looking at a genuine vintage Frank Olive felt hat, chances are pretty good it’s rabbit or beaver-blend fur felt, not basic wool.
