I have both the original and the repro of this pattern and I haven't decided which version to make. I have compared the pattern pieces for both versions and they are very different.
ohhhh man, that's so annoying! I finished making the dress on Wednesday and it didn't turn out brilliantly (though I am a perfectionist ). Now I wish I'd sought out the original! I expected that the reprint pattern would be easier to fit and use but we had real trouble. I've only made two other things, but I was surprised that I found my 50s/60s patterns easier to use, make and fit than this modern one. Don't know if you read my blog post, but it took a lot of fiddling with the bodice, and it still doesn't sit right. Other than that we followed the instructions *exactly*. Obviously everyone's body is different, and it is a lovely pattern, but from my experience, don't expect it to be the best-fitting dress you'll ever make, at least if you use the reprint one!
