The duchess of Cambridge was seen Tues, June 4 making final preparations for the birth of the royal baby just hours after the Queen's Coronation Ceremony, the Daily Mail reported Sunday.

Kate Middleton shopped for soft furnishings in southwest London with another woman, thought to be her lady-in-waiting. The duchess was reportedly searching items to decorate the new nursery at Kensington Palace in London.

Although Middleton had sported a daisy lace dress with silver grey ribbon detail and a peach silk jacket at the ceremony, she changed into a navy blue dress and magenta cardigan just before heading to the shop.

The front of the store featured curtains and items of a light blue color, but, it was not for certain which color the duchess bought for the royal baby. According to a report, the duchess chose beige and brown fabrics.

"Kate was fascinated by all the designs and picked out two," a source told the Daily Star on Sunday. "She had very definite ideas about what she liked. It was boiling hot outside so the door was open."

The source said that the duchess was feeling warm, so the insider offered her a drink. "The duchess was charming and so lovely. She didn’t put on any airs or graces. She said she’d got so many ideas after coming in," said the insider.
