The combination of the fashion world and social media usually has a negative effect on young people's mental health, but there's one woman who's hoping to change all that - AnneMarie Tomchak joined Mairead to tell her all about it.
AnneMarie has a background in both fashion and tech, and when a friend told her the story of her friend losing her 23 year old daughter to suicide, AnneMarie found a way to bring fashion and tech together to help.
She founded the ShareJoy initiative which will use Depop to sell pre-loved clothes donated by 20 accomplished Irish woman to raise money for Pieta House.

You can buy an item from ShareJoy's Depop, or list an item of your own and donate the proceeds to ShareJoy who will give all the money raised straight to Pieta House.
AnneMarie is hoping to do a new edit once a month on Depop to continue raising money, and also to increase awareness of circular fashion.
