Catherine's Dark Navy Cardigan 0x (14/16W)

After much contemplation over whether this is dark navy or black my boyfriend and I came to the conclusion it is navy. It is very difficult to tell. The sweater is a soft cardigan that is open knit on the shoulders. It's a 0x which is a 14/16W. Fabric is cotton and acrylic. It's an open cardigan so there's no buttons.
