IZ Byer 1-Piece Short-sleeved Black and White Cardigan and Tank

The picture doesn't do it justice (sorry!), but this short-sleeved black and white gently ruffled tank (polyester) and short-sleeved cardigan (rayon) is a in a trendy pattern and so stretchy and comfortable, you won't even feel like you're dressing up - but the look is perfect for a night out or a fancy work event. Size small.
