The Princess of Wales's outfits are analysed every time she steps out, but on World Mental Health Day 2023 back in October, she chose her accessories with particular care.
Kate kept a promise as she donned a very special pair of star-shaped earrings given to her by a grieving mother at Maidenhead Rugby Club last June.
Sarah Renton's daughter, Issy Phipps, tragically took her own life at the age of 17 last April, having struggled with depression.
The teenager's cousin, Sophie McGown, owner of EAR SASS, created the pair of earrings in honour of her "shining star" Issy.
Sophie has been donating £5 from every pair of the Issy Star earrings, £25.50, that are sold to a wonderful mental health charity, Brave Mind.
The Kate Effect struck once again with sales soaring after the Princess' first outing in Birmingham last October and orders being shipped around the world.
The Princess wore the Issy Star earrings for a second time just days later at a SportsAid mental fitness workshop in Marlow. In January, fundraising hit over £10,000 for Brave Mind, and since then, Sophie has created a special new pair of earrings, £27, named in honour of Catherine, the Princess of Wales, which launched this week - and have already sold out!
During a very moving conversation, Perthshire-born jewellery designer Sophie spoke to HELLO!'s Royal Club about the impact the Princess of Wales has had on EAR SASS and what it was like to be invited to her Christmas carol concert at Westminster Abbey last December.
Speaking about the first time Kate stepped out wearing the Issy Star earrings from EAR SASS, Sophie said: "If I could use one word to describe how it made me feel, it made me feel strong. We were going through such heartbreak and grief when Issy took her own life.
"It just gave me this incredible strength because I wanted so much to raise so much money for the charity in Issy's honour when Kate wore them. Not only wore them, but on a day that that was so significant to me and my family [World Mental Health Day] and on a day that we knew was pending that was going to be very difficult."
