Hi Em
I found some great hats on www.headcovers.com they are based in the USA but have a huge range of hats of all sorts and colours. The postage is also ok. I got 4 hats from them and have worn them heaps, they are all 100% cotton which you need in the QLD summer. I got a lovely white one with a peak and it's my dog walking hat. The dog now knows when we are going he loves the hat more than me !!
Also I found a website in the UK - www.nicolajane.co.uk who specialise in bras and swimwear. I bought 2 lovely bras from them followed their measurement guide and they fit perfectly (36DD) the prices are a lot less than here and the postage six pounds 50 pence (About $10) was good. In the UK you don't pay tax on mastectomy bras which keeps the price down would be good if they could do that here! Also Marks and Spencer have an on-line shop and now ship to Australia they also have a range of pretty bras with matching undies and lots of colour too. Again the prices are good and they also have reviews on the products from people who have bought them so gives you a good idea how others have got on. Not sure of the website address as I get a weekly email from the store but google Marks and Spencer and is sure to come up. Am waiting to finish my radiation before I order any more undies. Actually got a cheap comfortable mastectomy bra from Target last week and is great!!
Good luck and am sure you'll find something.
