I adore Topshop jewellery! I just wish I could afford it haha. When they drop a sale though, it's the best thing ever, I picked up the collar here for £2 from £14! missing a sequin but easily replaceable. It sits really nicely around the neck and is super feminine.
The only downside is that it looks like a choker, but the color is gorgeous and the length of the chandelier is alright. :)
I love topshop's jewellery but it's so overpriced - the sales are brilliant though.
