Minnelli’s hair and makeup may be memorable, but the legend says she doesn’t “have a particular beauty philosophy” that guides her iconic look.

Her words of wisdom: “Just make sure you look good before you walk out the door!”

Minnelli also says she has no plans to switch up her signature hairstyle, telling PEOPLE, “Are you kidding? Change my hair? Nay!”

“I just remember that the last thing Mama always did before she walked out the door was to spray herself with fragrance,” Minnelli says.

Garland would also have a rose named after her, and that flower would become the central note in the fragrance she, Luft and cosmetic chemist Vincenzo Spinnato (pictured below) released this month in a limited-edition bottle (above).

“I was most interested in trying to capture overall memories and thoughts of Mama with this fragrance,” Minnelli explains.

Minnelli thinks Garland would approve of the finished product: “I believe my mother would be happy, and she would say ‘That’s it!'”
