Holed up above Swanston Street for over a decade now, this second-hand goliath is one of the largest vintage stores in the country. With racks packed full of one-of-a-kind fabrics cut into new fashionable styles, old leather boots and bags at bargain prices, and a huge collection of band t-shirts, Retrostar is a destination in itself. It's easy to lose an entire afternoon trying on countless outfits, flipping through the styles of yesteryear and swiping free lollipops from their friendly service counters. Bonus: they also regularly host warehouse sales with thousands of pieces priced at just $5. Be sure to get their early to avoid the carnage.
