I’ve gotten several inquiry for this pattern. Thank you for your interest but unfortunately, I didn’t write it all down as I was knitting it. It was another one of my “wing it” project.
I used the following pattern stitch and knitted following the shape and length of an existing sleeveless t-shirt of mine.
The wavy effect at the bottom will appear naturally as you commence further up with the pattern stitch. No extra work to make that effect ;)
As for the ruffles, PU from midway of sleeve edge and worked in stockinette stitch. I YO after every K stitch.
