"It was fascinating learning from these incredibly talented women, all using their voices to shout from the rooftops about combating modern day slavery," Eugenie captioned the photos she posted to her Instagram.
The 29-year-old’s post received praise from her followers, while others suggested that she should "team up with Meghan" to continue her mission of raising awareness.
Both women are keen activists for women's rights.
Princess Eugenie founded her charity in 2013 to support vulnerable women and children.
And in September 2018, she joined a UN mission to Serbia with the UN Trust Fund to End Violence against Women.
Meghan has also worked with the UN, and gave a now infamous speech about feminism and women’s rights at the UN women’s conference prior to joining the royal family.
The new mum is also a patron to Smart Works, which helps unemployed and vulnerable women regain the skills and confidence they need to succeed and return to employment.
