This is very important. So far, I think my Diva has been knitted to the right measurements and it fits me well, pre-washed:
I think if I want, I can even start weaving in the loose ends and wash it and wear it as a vest! Isn't it lovely?
My swatch hasn't changed too much in measurements after wash. But I read in KR Forum someone's Bellerina was blocked to 62" instead of the intended 56" ... and I don't think it is wearable without going through a bath ... the yarn is a bit rough before wash. I am keeping my fingers crossed for this project.
