If you are looking to sew some leotard or swimsuit patterns, here is a guide to get you started.

Sewing Leotards and Swimwear

Patterns

First, you are going to need a leotard pattern. Once you have the basics mastered you will slowly get confident enough to hack patterns to make your own custom creations. If you are a first-time leotard sewer I recommend #4 for a leotard or #1 for swimwear as they are a great basic pattern with nothing tricky.

Buying Spandex and Lycra

If you are stuck where to buy Spandex and Lycra for your leotards and swimwear then why not buy online. Here is a guide to some great online shops selling stretch fabrics.

When starting, try and choose matt or satin finishes of fabric as these are easier to sew. Thicker fabrics are also better as they won’t need lining and don’t overstretch in your machine.

Always check that the fabric has a stretch factor that is suitable for your leotard pattern. The Treasurie leotard patterns use a stretch factor of 75%. This means that 4 inches of fabric will stretch out to 7 inches.

Sewing Leotards with a Regular Sewing Machine

STITCHES – You don’t need a fancy serger or cover stitch machine for sewing leotards. Leotard seams can need the same amount of stretch as the fabric so that the stitches don’t break with active bodies. A simple zig-zag stitch on a narrow width setting can create durable leotard seams.

Learn all the tricks and tips and best machine settings to get great results with just a simple zig-zag stitch and your regular machine.

MACHINE FOOT – If you have a fabric that is a bit sticky, a Teflon Foot can prevent skipped or uneven stitches.

NEEDLES – You will also need stretch needles rather than your regular universal needles. For Lycra with lower stretch factor, ballpoint or jersey needles can sometimes be used but you will get the best results with a stretch needle.
