I really like this top. I put a thin layer under the top layer and that worked out well. I think it would of been too heavy if I did all the layers in the same fabric. I actually didn't intend on doing it that way, as I didn't buy enough fabric and had to come up with a way to add to the fabric that I bought. Our mistakes often push our creative spirit to a better place.
The neck is designed somewhat low, so I brought it up a 1" and I think if I make this again I would bring it up more.
You can't see it very well, but there is a second layer under the back too.
