There's a really important message behind the dress Kate Middleton is wearing today.

Today, the Duchess of Cambridge, Kate Middleton, attended the launch of Family Action's FamilyLine, a UK-based helpline that's been established to support families and their caregivers. The mum of three met with young carers and heard about how they have to balance school with the duties of caring and also spoke to some of the volunteers who have recently gotten involved.

However, Kate's dress has also been getting a lot of attention for the green midi-length design is from Beulah London, a brand that donates a percentage of their profits to support victims of sex trafficking. According to the website, 10 percent of all profits are donated to The Beulah Trust which was set up to "to give grants that pay for skill courses giving women who have been victims of sex trafficking and abuse the chance to find work, generate an income, and live a self-sufficient life, free from abuse". Beulah London was founded by Natasha Rufus Isaacs and Lavinia Brennan in 2010 and The Beulah Trust was set up after the two women volunteered in Delhi and saw first-hand what women living there were subjected to. The luxury lifestyle brand isn't cheap with some dresses priced around the £500 mark but it's clear that both Natasha and Lavinia have big plans for the trust and want to further the important work that it does. Kate's dress isn't available to buy just yet but it's very likely to sell out once it does.
