They won't.  Ease is built in - the measurements are not used as the finished garment measurements.

That is not my experience.  I requested a dress pattern and gave my measurements and it was too small as there was no ease, it was literally the meaurements I gave (and I double-checked my measurements , both measured and input before sending in so no user error).  I subsequently ordered a shirt with ease included in my measurements and the fit was fine.  Although thinking about it, I may have had to take a bit of ease out of the shirt as I don't like things too loose and it was a looser fit style.  Maybe I was just unlucky with my dress.

Kona Solids ... ???

Just what I was going to say!

The bodice overlay will be attached at the waistband and that will come over the shoulders

Apologies, I thought is was going to be strapless.

Re the boning, just make sure that the end caps are on securely for the spiral boning and I would even consider covering them in tape (plumbers tape) so they don't rip through the fabrics.  I would also use flat steels where there is no need for any movement in the steel.

Croeso @SewAnwen  Looking forward to seeing your makes!

@Puzzler   ooh, is that a weekend "sewing" job for us, duct-taping you to make a Puzzler dress form? 

@Iminei don't you find quilts on the back of chairs look messy and attract dust ?

I have blankets on the backs of my chairs/sofa and they don't attract any more dust that the furniture on which they live.  I try to keep them neatly folded.  I like them there; it looks cosy and snuggly.

I have the Morplan patternmaster (which I bought online millions of years ago) and I love it.  It has straight edges, angles, the curves of a french curve, and more), it also has 0.5 cm increments up to 6cm I think it is using the straight edge, which is excellent for adding seam allowances quickly and easily.  Other than my metre rule, it is my most used measuring implement and is in fact used more than my rule.  Definitely worth the money.

That is very pretty @charlotte and gorgeous work as usual but you will need it to be made of firmer fabric than lawn.  It needs to support the boning and also the weight of the dress which lawn on its own just wont do.  Also the lawn will not be stable enough on its own and the seams may well tear under the strain.   Whenever I make boned bodices, I use tie canvas and lawn sewn together as one layer and this goes between the fashion fabric and lining (I don't tend to do separate corselette, but that is personal preference).
