I used the skirt of Butterick 5322 (fast becoming my Go-To pattern when I want simple pattern blocks to alter or add to something else), and drafted the top myself. This is really the simplest possible bodice pattern - a single pleat on each side, meeting at the center of the neckline. As the pleats are not stitched down, you don't even have to worry about getting the distance from the bust point right to avoid a dimple at the end of the dart - just fold things so they meet and it all work out!
The sleeves I figure out by trial and error - I think the next version I will move the arm scye just a touch further out on my shoulder, I bought it in quite a lot as the pattern block was much too wide on the shoulders and I think I may have over done it just a little!
All that hole-picking aside (I always want to get better!) I'm really pleased with this dress! I think I will be making another soon - probably in a lghter colour, to wear with a skinny black belt like the inspiration dress, and I may also try it with a pencil skirt instead of A-line.There's a couple more pictures for you below - the red is the original inspiration dress, and the second pic is a close up of the dress on my dummy.
