Jackie Kennedy's notes to designers to go under the hammer

Jacqueline Kennedy Onassis' timeless handwritten thank-you letters and a few dozen pieces of Onassis's personal memorabilia will be auctioned off in West Palm Beach.

Rico Baca, auctioneer and co-owner of Palm Beach Modern Auctions, where the items will go up for sale, said that the one thing that interior designer Richard Keith Langham, the photographer Bob Davidoff and former design director of Carolina Herrera Bill Hamilton have in common is that you can't do someone's clothing or someone's interiors or take their photograph consistently without them being vulnerable, People Magazine reported.

Baca added that her letters talk about her appreciation for what people did for her and it's a reflection of her style in the sense that it was old-school, that she wrote thank-you notes, that she was appreciative of people who were in service to her.

In one of her letters to Richard Langham, she wrote "What an eye you have and how lucky I am to be its beneficiary."

Onassis, who died in 1994, wrote to Bill Hamilton, former design director at Carolina Herrera, in one of the letters "I just love this suit and will wear it everywhere as I am so sick of everyone constantly in black."

Onassis wrote to Hamilton "There used to be a cinnamon suede overcoat that went with the long fur vest. It was lined with silk - it closed with little ties you knotted. You could wear it by itself on warmer days. I gave it away years ago because there was no room for anything with shoulder pads.
