Like another reviewer I wasn't sure if the white piece was a part of this sweater or not.  It is not.  I wear a cami or tank top underneath this sweater,the V is deep.  I got the dark blue color and really like it, it is soft and feels cozy.  I normally wear a medium and got a large and it fits a little loose but I wanted it like that.  I also like that the sleeves are a little longer, I normally have a hard time finding sweaters with long enough sleeves.  This is a great layering sweater.
