Getting Started
Choose any light knit you like. You'll also need thin velcro, a scrap of matching tulle, and small ribbon for straps. I also recommend a fine tip wash-away marker.
I used cheap fabric I got from AliExpress. Regular fabric stores should have higher quality fabrics with the same print. I don't recommend the AliExpress fabric, the the print flakes off, and oxidized to nothing after I washed it.
Align the fabric so that the stretchy direction is horizontal. Trace the pattern onto the back of the fabric.
Set your own seam allowance, as much or as little as you feel comfortable with. You can always trim it down later.
Sew up the sides. I trimmed it down a bit at this point.
Put the bit of tulle across the front side.
Sew across the whole top edge.
Trim away excess. Make a small cut where I marked in red, stop about 1mm from the seam.
Trim away excess tulle.
Fold the tulle back, and use it to neatly catch the edges of the fabric.
