Measure how long you want the bodice to be and then add 1 inch for sewing and cut your tank top to that length.
Cut your self some sleeve pieces. Mine are 10 inches long and then I curve one side. I wanted two layers of sleeves so I have the width on the two layer more shallow than the bottom ones.
Finish the straight edge of the sleeve pieces. I did this by doing a rolled hem on my serger but you can just do a narrow hem.
Gather the sleeves along the curved edge. I like to layer the two sleeve pieces and then gather them up as if they are one piece.
Next using a stitch that can give a a little, like a 3-step zig zag sew the sleeves onto the tank top.
To make the skirt measure how long you want it and trim the fabric to that length. Mine is 22 inches so I just cut along the fold for how the fabric came on the bolt. So for each skirt layer I have two 1 yard by 22 inch pieces.
Sew the short ends together.
For the top skirt cut the bottom edge off in an angle. Lay it over the bottom piece and see if you want to cut any more.
Hem the skirt. I used a serger to do a rolled edge but you can use any hem you prefer.
Now layer the two skirt pieces on top of each other and finish the edges with either an overlock stitch or zig zag.
Treat both layers as one and gather the skirt. This is my favorite gathering technique.
With right sides together pin the skirt to the bodice and sew to attach.
Turn right side out and you’re good to go!
