Perfect gauge on 6.5mm, both sts and rows.

I’ve used a bottom up construction before and it’s easy knitting, but more difficult to judge the length of the body/sleeves. Where the inside sleeve starts depends on the body width, and also yoke length and armhole depth, which are the last part to knit.
Looking at the schematic, and knowing my row gauge measured up, I decided to knit the body length as the pattern, but add 2” to the length of the arms giving an inside sleeve seam of 16.5” My normal inside sleeve is around 19”, but the armhole schematic depth and width of the body means that the underarm starts partway down the arms.

I chickened out of using a tubular cast on with this yarn, so used an alternate cable cast on for the body and sleeves instead:

Knitted the body to pattern (i.e. 13” from hem to armhole).

I started the sleeves without a 6.5mm 12” circ, which is my normal method of knitting small circumference. I don’t think they’re even available in that size…
Made a mistake on the 1st sleeve by casting on 28 sts on 4.5mm (rather than 34sts), then continued the ribbing on 4.5mm instead of changing to 5mm!
I realised my mistake when it came to the first increase round, so after trying it on I decided to modified the sleeve to do 2 increases at a time instead of one, giving me the correct number of sts at the end of the increases.
My wrists are a tiny 6”, and they fit without slipping down.
For the increase rounds I did k1, M1L, knit to 1 st before the end of round, M1R, K1.

I normally avoid Magic Loop, but found this really simple method, which avoids ladders:

I bound off the neck loosely, but this yarn has no stretch and I couldn’t get it over my head.
After taking the bind off out, I used an easy Lace Bind Off technique on 7mm. It’s stretchier, but still looks like a regular Knit bind off.
K2togtbl, slip that stitch back (purlwise, without twisting) on the left needle and repeat to the end.
Now it’s perfect, and not too big, either…

I didn’t stretch the hem out at all, as my hips are small.
