There's a difference between a jacket and a coat

This, I have learned, is most obvious when you are trying to sew a light jacket using a sewing pattern for a coat. There's a big gap at each shoulder which is calling out for a shoulder pad - though I really wanted to avoid using them because my shoulders are wide enough (or maybe they just look that way because I'm sort of wide overall).

Also, I get why tailors use all that extra interfacing and stiffening now - it's to fill in the gaps between your body and the jacket so that you don't get lots of unattractive wrinkles near your armpits when you wear it.

Still, I'll do what I can. This is to be my non-classic denim jacket which is definitely not a denim blazer (cos I hate those). The pattern I used is the one I used to make my spring coat a while back.

I've shortened the skirt a lot, have added rounded sleeve tabs, will add a back tab, and plan to have 3 button fastenings: where the skirt joins the bodice and; two more between there and the collarbone.  I also plan to use dark pink bias binding to cover all of the seams which aren't flat-felled.
