• Kate Middleton wore a face mask in public for the first time and a necklace with her kids' initials
  • The duchess of Cambridge's mask is affordable as it is retailed at $20 only
  • Middleton's mask was designed by Amaia, Princess Charlotte's favorite brand

Kate Middleton was spotted wearing a face mask for the first time in public when she visited Baby Basics UK in Sheffield.

The Duchess of Cambridge sported a reusable cotton mask on Tuesday when she stepped out to help the baby bank unpack donations. Middleton's mask was designed by Amaia, a children's designer in London and among her daughter Princess Charlotte's favorite brands, Vanity Fair reported.

Middleton's mask is affordable because it is retailed at $20 only. It's also charitable because 30% of its proceeds go to NHS Charities Together.

The duchess opted for the Liberty London's "Pepper Tana Lawn" micro-floral print. She paired it with a simple, white double-breasted, belted dress by Suzannah. Prince William's wife, who is popular for recycling outfits, first used the dress in Wimbledon last July. She also sported a pair of Tabitha Simmons lizard-print Dela heels and accessorized with a necklace with her kids Prince George, Princess Charlotte and Prince Louis' initials.

“Over recent months, I have heard from families who have been supported by baby banks through the most difficult of times and I have been deeply moved by their stories,” the Duchess of Cambridge said during the visit.

"Baby banks are driven by incredible volunteers, demonstrating the power of community spirit in supporting families and coming together to raise the next generation.Thanks to the generosity of the companies taking part in this initiative, baby banks across the UK will be able to support even more families through this particularly challenging time.”

Meanwhile, according to royal correspondents Omid Scobie and Carolyn Durand in their book "Finding Freedom," Markle was scolded for wearing a necklace with her and Prince Harry’s initial. The duchess was allegedly distraught, frustrated and emotional after being told that her accessory would “encourage the photographers to keep pursuing such images — and new headlines.”

"They make out like I'm to blame for these pictures, that it looks like I'm encouraging them, that me even acknowledging the cameras may not be sending the right message. I don't know what to say. It was only yesterday that people online were saying I look miserable in pictures, because I was trying to just ignore the [photographer],” Markle said.

Prince William and Middleton greeted Markle on her 39th birthday on Tuesday. However, their post received mixed reactions from Twitter users, with some calling them hypocrites and bullies for not treating Markle well when she was still with the royal family.
