So for the summer months I have a lot of really great maternity dresses, but my shoulders/upper arms are just AWFUL and most of these dresses are sleeveless or spaghetti straps. I don't want to cover the top of the dress up with a short-sleeved cardigan... I just want something that covers my shoulders and the tops of my arms, maybe a cap sleeve, and doesn't extend to the waist.

Something like this, but without the lace, and simple:

Anyone remember seeing anything like this for sale anywhere? I need one in black and one in white.
