Sorry, I didn't notice this thread until now. Honestly I haven't really done much more research on this since I started this thread over a year ago. The stripes on the Whimsic Alley sweater aren't completely accurate in size, and I am not 100% sure about color.
If there are better options out there it would be nice to see, but I am completely satisfied with what I got from Whimsic Alley. They are perfect for cons and also movie openings.
