Asymmetrical Vogue

This dress is an out-of-print Vogue, 2797, that has been idling in my pattern drawer, waiting for the right fabric to come along.  The style is looking a little dated, but it seemed a shame not to make it up after all this time.  There are asymetrical dresses around at the moment, but they tend to have much bigger sleeves.

I have included a few photos, so that you can see all the asymmetry in all its glory. 

I sewed it at my mother-in-law's kitchen table whilst on holidays.  I have started taking my sewing machine on holidays with me.  This was a good dress for holiday sewing because it needs no notions...no interfacing, no zips, no buttons, no clips, no stabilisers...it is just fabric.  The pattern is cut on the bias.  The diagonals in the fabric do not line up with the bias, so I was not sure whether to cut it on the straight, or to match the diagonals or go with the bias.  Rather than dilly-dally with indecision, I just cut it on the bias as indicated by the pattern.

The off-the-shoulder section is cut as a different piece than the sleeve-and-shoulder.  Amazingly, this dress does not gape at all, no matter which way I bend and twist and turn.  I am wondering if this is because the 2 bust sections are cut on opposite biases?

I'll pop the details in a pattern review, for anybody who has this pattern lurking in their collection.
