So I decided to just undo my work and try and fix it that way. The gray one was about an inch bigger. As you can see from the picture above.
So, here are the berets together. She wanted the second beret (the gray one) to be exactly like the first one. The one thing that I am realizing is that I have to be aware of the yarn that I use with each project, especially if I am making things for somebody. Because if they are asking for the exact same size each time, for whatever I make, not just hats, I am going to have to make sure to get yarn in the exact same yarn weight or size, I guess you could say.
