the first one is mypetsquare, which i believe is an australian brand. i don't recall the cost, around $120, i think? so pretty reasonably priced. i found it very 80s avant-garde, i don't know where i'd ever wear it but it's an urgent want.
the second one was shona joy, and i lovelovelove it! i'm absolutely going to buy it. it fit my body so well. i didnt get a photo of the back, but it had a low-plunging backline. i especially liked the way the straps were braided, i thought it was a cute touch. about $170.
if you're wondering, my nail polish is an unidentified dior colour received as a gift from a lovely neighbour - it's beautiful, right?
