Sewing starts with...

 Sewing starts with the proper fabric.

I prefer natural fibre almost always, except some special occasions.
But for everyday wear and everyday comfort natural origin of your material is essential. 

 Everyday garment shouldn’t look plain and simple. Let's use print of the fabric, try some geometric and free forms, add lace of the same colour...

And don't hesitate to put your jacket into the washing machine - cotton lace is OK with washing, if it had passed pre-sewing preparations.

 No symmetry here.
Non-symmetrical hemline and neckline. And embellishments as well... Wait! At least sleeves are the same.

 Helen, who ordered this jacket planned to wear it with black leather skirt.
