I found the instructions on this version lacking quite a bit. They instruct you to add bound button holes to the front placket but don’t tell you how to do them, they also don’t remind you to add windows for the buttonholes on the facing of the placket. Also despite needing buttonholes on the cuffs, they forget to tell you that as well!
The Simplicity pattern does have a pattern piece for a tie-belt, which you could draft up easily anyway, but I think it’s also a nice piece to make this dress easier to wear for work.
Details wise the collar is very simple, it doesn’t include a collar stand or things like that so it just lines up with the placket and is encased in the facing
|Bound Buttonhole front|
If you see in the top button hole it doesn’t line up properly to conceal the raw edge, but the one on the bottom does. It’s pretty easy to avoid this mistake. You just need to be careful when drawing up the little windows and being sure to line them up before sewing.
