It is easy to size up or down as a whole or to adjust the individual panel sizes based on where you want the changes. You could also lengthen it by repeating rows in any of the sections, but you will have the best luck if you add rows in the “solid” rows (where there are no skipped stitches).

It is currently graded for sizes XS through 4XL, with the sizes being grouped XS/S, M/L, XL/2X, 3X/4X, and with the finished size of each varying by about 1.75 inches in each of the panel widths.

These are easily customizable if you want looser panels in the front, across the back, or looser fitting sleeves, just make sure that you add stitches in odd numbers for the ch-1 spaces to line up and look right. If you want a size larger than 4X (or just want a looser fit) you can size up super easily by simply adding stitches at the beginning or throughout the panel(s) depending on where you want a change.
