I am making it from a wool double knit (maybe a blend) that has quite a bit of stretch but no lycra. The idea of making this dress from a woven has zero appeal to me. But initially I chose my size from the available choices (XS-S-M-L) conservatively based on my measurements. S is supposedly 8-10. I figured I could take it in and cut it down once I could see how it was going to fit.
As I predicted, the fit was very sloppy. See for yourself. It's too wide from top to bottom. The armscye is very low. Also, as I moved around I realized that the dress was rotating back, suggesting to me that the back was too short relative to the front. And the back is just generally baggy.
So ... alterations. First, I sewed it back at the side seams to size XS above the waist and a smidge wider at the hip. At the shoulder seams I sewed it to XS. I took two vertical darts in the back and sewed out a third vertical dart in the CB seam.

I shaved out some of the princess seams in front to create more waist darts, in effect.
Next and hopefully last, I will have to cut the front neck lower to match the amount of depth I took out of the shoulder seams.
So, not such a simple sew. But I think I will like this dress once it is done.
