I started working on the fancy dress with the matador hat, called a montera. I stated before I am not using period correct fabric as this is a costume and will probably not be worn more than a couple of times.
Here is a picture of an original montera. Mine does not look quite so good; more like a smoking cap with bulbs attached to the ends.
I started with a buckram band covered in black fabric.
I then added the top. It is a bit bigger than the top on the original and I did not decorate it as other originals have been. The top was based with buckram as well.
I then added the bulbs. These are supposed to represent the bull's ears. I stuffed these with fiber fill.
It's not perfect by any definition, but it gives the impression of a montera and the impression is really what is important for this rather than an accurate, exact copy.
