I haven't been at The Sting in ages, because their quality has been declining in the past few years (and their prices stayed above average), but now they have very nice items again.
The price was around € 30,=, and they have various colors (white, grey, blue, mint, pink a.o.).
The cardigan has 3/4 sleeves, which makes it ideal for summer. The front has some really nice lacey details to it and the fabric is of good quality and feels really soft! :)
Here's a close-up of the lace:
