Since this pattern is already a pretty tight fit, I just use the size my kids measure into. If you would like a tighter fit, size down but make sure to lengthen the pattern to the size your kid fits into.
*Note: This is just for the swim top, you will still need to use a swimsuit or undies pattern to make the bottoms.
1 – Fold Neckband and Back-band right sides together. Press bands using a heat suitable for the swim you are using.
2 – Sew along edge with a 3/8″ (1cm) seam. Turn both right-side out. Press both well.
Again, since this is swim, be careful with the amount of heat and time you leave the iron on the fabric. You don’t want to burn a hole in your fabric!
3 – Fold Back-band in half.
4 – Set aside.
Place Fabric B front and back sides RST. Sew along both sides but leave a 3″ opening on one side.
Turn right side out. Press seams.
Line up side seams, neck and back.
Sew along top leaving openings at the shoulders and back middle.
Sandwich each side into the shoulder seam openings, right sides together.
Sew straight across each shoulder seam.
Turn right side out. Press well.
Sew along Back-band opening.
Turn right-side out. Press well.
