Kate Middleton purchased new shoes for her children but forgot to bring their socks.

The Duchess of Cambridge was spotted with 5-year-old Prince George and 3-year-old Princess Charlotte shopping for school shoes, Hello! reported (via Express). Middleton brought her kids to try their new shoes but forgot to bring their socks as they were wearing sandals. So, they have to borrow socks from the shopkeeper so the kids can try on their new shoes with it and see if it truly fit them.

Princess Charlotte was back in her nursery classes on Wednesday. Meanwhile, Prince George made his first day of school at Thomas's Battersea in London. It was reported earlier that Prince William and Middleton would drop the two to their schools.

Last year, Middleton was not able to join Prince George and Prince William for the tot's first day of school due to severe morning sickness. The Duchess of Cambridge was expecting Prince Louis at that time, but she made it up to Prince George after delivering her youngest son.

According to an eyewitness, Middleton was seen dropping Prince George to school a day after giving birth to Prince Louis. Although some notice her, the fathers who were present were reportedly more interested in a Victoria's Secret model than the royal.

"No one really gives Kate a second glance when she does the school drop-off," an eyewitness said. "We have a Victoria's Secret model doing the school run, too, and the dads are far more interested in her."

Prince George is expected to be busier in school this year. The third-in-line to the throne will reportedly have daily assignments that include 10 minutes of reading every day. The school will also send him a spelling rule or pattern weekly.

Prince George's year-long curriculum includes math, English, science, history, geography and religious study. His special subjects include French computing, art/design technology, music, ballet, P.E. and drama.

On the other hand, Princess Charlotte's new classes include pottery and poetry. "It is a fun and structured morning with lots of free play where children embark on the first stages of learning to read, write, and to understand simple numbers with the minimum of pressure," the website read.
