LOCAL is key
Studying the Dress, Body, Couture subject last semester at UTS (University Technology, Sydney) really opened up my eyes to local designers and appreciating them even more. A key concept involved in making our world sustainable is to deal locally -buy your veggies from your local grocer who have been supplied by a local farmer, buy your clothes from a designer who designs locally and manufacturers them locally too!
(On the veggies part there's a really cool co-op happening on Fridays and Saturdays at the beginning of a little lane way between Regent and Kensington Streets, running off from George St. opposite the University of Technology Sydney. They offer really affordable fruit and veg. only taken from local farmers and some of their own backyard stock -check it out, it's honestly cheaper than the supermarket, has a nice ambience and is sustainable!)
