Couldn't find an expiry date on their site and I've never seen all their stuff on sale before (they do have a discount code for first time buyers: IMAHOMIE for 10% off).
If you're not familiar with HoMie, they are a Melbourne based business with 100% of profits going to help young people affected by homelessness. All garments are ethically made and they're pretty transparent with their manufacturing process.
Disclaimer: In 2020, they moved some of their manufacturing to a factory in China, but I think I'll stick to garments made in Melb.
Edit: Looks like anything that's "Ethically manufactured" is made in China. Would prefer if they outright said it was "Ethically manufactured in China" but I suppose they wouldn't be getting sales from people who think they're still all Aussie made.
