Floral viscose Chari dress

I cut a straight UK size 18.
I did a 5/8ths inch FBA and carried the extra width all the way down the front to the hem. This dress is actually an A-line shaped dress with no waist seam; the shaping at the waist is achieved by means of a casing and elastic.
As an added fit insurance I also added 5/8ths inch to the side seams from just above the waist down to the hem. Probably wasn’t required.
The upper arm size for the size 18 seems to be wrong. It is stated as being much smaller than what it actually is. I altered the sleeve to be a short/ cap sleeve with a 1 inch full arm adjustment.
I did a 1 inch full bum adjustment.
I would advise to stay stitch the front and back necklines and ruffles.
I did a narrow hem on my ruffles.
I lowered the front casing point by approximately 2 inches. I also sewed my casing on the inside, rather than the outside as directed.
If making this again, my front shoulder seams need to come forward by approximately 1 inch?
I added ties in the back to secure the shoulders.
This is one of those throw-on-and-go dresses which will be perfect for hot weather (if summer ever comes!) Full details on my blog: https://sewmanju.com/2019/06/17/schnittchen-patterns-chari-dress-diy-pull-on-floral-viscose-ruffle-neck-dress/
