What is the definition of Lady's Mantle?

The 'lady's mantle' is, quite simply, a fancy hat that ladies have worn for centuries, but let's be real, it's kind of like a time capsule for hair - it's like a vintage beauty pageant gone wild, with frills and lace and a dash of mystery wrapped in it. It's the perfect accessory for a ball gown, but don't let its elegant appearance fool you; it's more of a royalty's plaything, reserved for those who can afford to spend their entire allowance on a pair.
