Let's take a look at the pattern a little further:
Size Made: Based off of my measurements and against my better judgement, I made a size 10... I really wish that I would have made a size 8 or cut the pattern down to a size 6. Perhaps it would have had a little less 1980s feel going on in the shoulders if I had.
Fabric: The pattern suggest 1 7/8 yard for a size 10 made in version B. Depending on the width of your fabric, I can attest this is fairly accurate.
