Late Victorian Blouse Mock Up

Hello there, I've been long planning a gingham Late Victorian outfit. I ordered the fabric for the blouse ages ago but when it arrived it turned out to be too thick, so I used it to make an apron. Long weeks of looking for a suitable fabric followed. At last I could find a 100 percent cotton fabric that wasn't too thick. And now I'm too scared to cut into it, so I decided to use a cheaper fabric to make a mock up. Of course, as usually, I made it wearable.
