I am so so happy….It’s finally done, it took longer than expected but I enjoyed every bit of it

The review will be very short because I didn’t use a new pattern, I used one of my already fitted patterns simplicity 3628  because I didn’t want to do two complicated things at the same time (fitting pattern and cutting plaid fabric).

 However, I went a bit out of my comfort zone; I did a little bit of tailoring.

Here are what I did differently

I did  FBA which I didn’t do with the first version

I interfaced the back and the upper sleeve using a biased cut interface

I used neck tie interface for the armhole

I cut a separate back neck facing….

I bagged the lining

Also instead of using a rat tail I used in the previous jacket, I used thin black elastic for the loop .

Finished project pictures.

My question 
The problem I have is with the closure to use. I used a temporary black button for now.
Do you think this is nice enough or I should use another color of button,  a hook, or I should just leave it open? This will be mostly office wear , I want something both office appropriate and that can be worn outside office . I will really appreciate  your suggestion(s) …
 Enjoy the rest of the week
