I got mine from Best & Less for around $20 each. I don't remember what brand they were, but they are like the normal t-shirt bras you can get. They have slight padding, no wires & come in pink black or white. The back can either be plain or with lace.
I have these too! I have 3 of them. Um Slim fit or something like that they are called. There in Big W as well. Actually I noticed Bonds have one the same in Big W too. The bonds one looks a better make actually.
