Color Block Dress

I included a picture of the pattern for a reason. You can see that the two-colored version is sleeveless. None of the short sleeved versions are in two colors but I wanted short sleeves. So, I modified the pattern to include short sleeves, which took some work because the top of the two color version has a facing across the front and back, not just armholes and neck. I wanted to add a mandarin style collar, which I borrowed from another McCall's pattern; but. after cutting out both the collar and the interfacing, changed my mind and just kept the round collar (easier to wear necklaces with). To my surprise, as I was finishing up the dress, I noticed the Joann's ad with the same pattern, two colors, and short sleeves! I know it's just a drawing but who at Joann's is reading my mind?
