I can't help with USA vs. Australian sizing differences, but I second what mbmundt said. All the Cathe shirts I have ordered run small. I would order at least one size up.Hoping you can help. I want to add a Cathe t-shirt to my order, but unsure what size to get. I am usually a size 8 Australian
OMG! ROFL!but the easier the better! I don't even want to admit how long it took me to put on a sports bra that arrived with the racer back style... I had to watch a youtube video LOL...
