She wasn't listed as wearing a Lilli Ann suit but once I saw her, I immediately knew she was wearing a Lilli Ann suit. She is quite chic in her Lilli Ann suit, accessories, and I'm sure wearing a nice tint of lipstick. I wonder the event that she might be going to. I'd love to see more vintage ladies wearing Lilli Ann, as I'm sure it was very popular during this period too.
Here is an ad of this suit from January 1956. Via Flicker.
