How would you modify/tailor a Finfolk fabric tail?

[Naiad Rose]

I'm not quite sure which forum to put this in. I was wondering if anyone has any tips on how to tailor a Finfolk fabric tail down 1 or 2 sizes? I've lost some weight so I need to take it in a bit. I'm not sure if I should just try working on it the same way I'd work on a normal dress maybe?

Yea, its the same method as a dress. You just take in the side seams.

I turn the tail inside out and sew a new seam with a zig-zag stretch stitch.
Remember if you want to take it in 1 inch, the new seam will only be 1/4 inch in from the old.
