Even though the silk is a precious material to wear, its maintenance is a nightmare. You can't just throw it in the washer and don't even think about the dryer. You can't put it to direct sunlight, you have to be careful with rough surfaces and its mortal enemy it's red wine... which is not very compatible with my personality but... still, a girl needs at least one piece of clothes made out of silk.
But the plan of joining them in the back didn't work as expected because there was too much shapeless fabric. My derrière looked like I had a pony tail... I could even make a parody of the Kim Kardashian "break the internet" picture.
So my plan b was joining the ribbons underneath the blouse. Just like this picture. For this, I had to make two big button holes in the back of the blouse, parallel to my spine. Once the buttonholes were finished I could pass the ribbons through them and attach them together with buttons.
The last step was finishing the hems and the size of the arm holes.
I have to confess I liked the final result. It's a fresh brand new blouse to go out and grab some martinis with my husband... because... you know... silk doesn't like coffee either.
