Well, this photo certainly shows quite a bit of cleavage! You certainly don't have to show that much... (I'll work on getting another photo)
This ribbed sweater has wrap styling in front and back, which creates a V-neck front and back as well. The back has a strap at the top of the opening in order to keep it from slipping off your shoulders. The lace sleeves add a little extra interest on an already pretty piece.
You can wear this on its own, or maybe close it a bit with a pin or button. Would also look great over a lace bralette or a pretty camisole.
