I prefer crochet to knitting.

Me too and I am an almost lifetime knitter; my grandma taught me when I was very young, maybe about age 7.

I find crochet more portable and also very mindful, due to the constant counting required, or is that just me?

Ooh thank you @Ouryve   I've never looked at their site before.  I have now and have made a purchase of a bottle green viscose crepe fabric with pinky/peach polka dots, which will be perfect for my 1940s wardrobe for an event next year!

Ooh, I'd never heard of them until know.  What a fabulous resource.  Thank you Morgan

I have converted flares to skinny jeans but to be honest, if I were you I'd go on Vinted & buy size 8, sell your 10s on there. Jeans altered 2 sizes will never look good (well, @Sandra could make it work). Your tops will be perfectly possible as @SewRuthieSews says. I put the top on, inside out, then pin out what needs to go. However that may not work with your scoliosis in which case pin with it on RS out then transfer the markings to the inside. Ideally get a friend to help with the pinning.

Just to say that you should never put items of clothing on inside out to alter as everyone's body is asymmetrical.  Put it the right side out and it you will fit to the appropriate side of the body.

That is looking much better.  There seems to be some excess fabric at the side front and backs.  It looks almost as if there is too much length in those bits. 

The front waist looks to be dipping a bit.  As mentioned before, and as ohsewsimple said,  put a tape around your daughter's waist.  Get her to lean to one side and where her body folds, that is her natural waistline (which is often different to where we think it is).  Pin that side in place (with the bottom of the tape on her waistline) and then repeat on the other side.  You then need to make sure that it is straight and perpendicular to the floor across the front and the back.

Once you have got all these bits sorted, you can then proceed to creating the dress pattern.  Do not start this though, until the bodice block in 100% correct.

A number of things have been cited related to cost of living, but probably most importantly, Amazon now holds onto their money for 10 days before paying them which puts a huge strain on a small business and was probably the final nail in the coffin.
The story is in their blog

It's a shame as they are my go-to online store.

Could I ask, did you sort out all the fitting issues on the first toile fully, before moving onto the pattern?  I cannot see where the bust point is marked on this, nor where the waistline is.  It looks to me like the front waistline is dipping down but that could just be the angle of the photo.

To echo Brenda, you need to have the darts in the skirt and you also need to build in ease in the skirt (else she won't be be able to sit down in her dress).  The darts of skirt should line up with the darts of the bodice.  The wrinkling, particularly in the skirt area, could be that the skirt is too tight, making everything ride up.  Once you have that sorted, then you can better look at the bodice.  It might  be that you need to pinch out the excess in the bodice back.

I'm not sure what exactly is going on with the shoulders/arm syce, particularly as these seemed to fit on the toile.  It looks to me as is the shoulders are being forced to sit too wide, which is possibly causing the rucking at the shoulder/arm scye and looking at the back, the shoulders/upper back look too wide and are going down onto the upper arm, further suggesting that they need pulling up onto the shoulders more.  I would consider moving the shoulders of the dress on the physical shoulders more and making the V of the front bodice less dramatic.  The wider the neckline, the higher the risk of the dress falling off the shoulders.

I note that the back darts are at an angle, which is not usual.  Darts (with the exception of a french dart) generally go up and down.  That's not to say that you can't do that, it could be a style line.   However, being as I would strongly recommend that this is boned (to stop the dress falling off the shoulders), you could use the angled darts as a basis for the line the boning would take on the back. Also, you appear not to have gone for a princess line on the back, which is unusual when there is that styling on the front.
