BONDI BATHER High Leg One Piece Swimsuit Black

I have several of these swimsuits, they are all unworn & washed once, they have all had their tags cut out (see pic) so please read carefully one of them still has the size in it which is a US 6 & I have another one that is exactly the same size so Must also be a 6. I also have 2 more which are slightly smaller than the 6’s (see pic) so I would estimate them to be a 4 but if you require measurements let me know :) These are really high end swimsuits that retailed for well over $100 AUD each
