Victoria Beckham uses daughter's drawing for charity t-shirt

LONDON, Nov. 18 (UPI) -- Mom-of-four Victoria Beckham is putting her daughter's artwork to good use.

The 42-year-old designer chose 5-year-old Harper's drawing for her new World AIDS Day t-shirt design, which she revealed on social media this week.

"Thank you @voguemagazine! My #WAD2016 t-shirts available tomorrow at #VBDoverSt and victoriabeckham.com x VB," she captioned a photo of herself in the shirt.

Beckham was named a UNAIDS International Goodwill Ambassador in 2014 and designed her first World AIDS Day t-shirt the same year. She told Vogue the role is "a huge honor" that she's taking "very seriously."

"This year, for the first time -- and along with a little help from Harper -- I've created an adult's t-shirt with a matching mini version for children," the star said.

"We have a real opportunity to totally eradicate HIV and AIDS for the future, however, we need to keep going to ensure global access to treatment to ensure that no one is left behind," she added.

All profits from the 2016 World AIDS Day t-shirts will go to Born Free Africa, an organization focused on ending mother-to-child HIV transmission. World AIDS Day takes place on Dec. 1 each year.

Beckham shares Harper and sons Brooklyn, Romeo and Cruz with husband David Beckham. She came to fame with the British girl group the Spice Girls and has since launched several fashion lines.
