Denim jean jacket

I bought this in Australia. I can't remember where. You will see the tag says size 8. If you convert Australian sizes to Canadian sizes, a size 8 AUS is a size 4 CAD. The fabric is a stretchy cotton. Not too stretchy, but just right. It fits on the tight side, so I would say a size 2/4 would be the best fit. I am a size 4. It's in really good condition. I only wore it a handful of times.
