I've got an excellent pic of me at my top weight, in period costume.
This year, I wore the same clothes to the same reenactment, and took a similar pic. Boy there is some real difference!
I will have to make new period clothes. The old ones didn't fit me this year.
You can see a combined pic here:

I love the costume, btw. If I may ask, did you make it from a pattern, or just wing it?
