Things you will learn
The ready-made pattern is approximately for size 40-42; for a larger size, cut it open and widen it with an insert.
Each leg is cut as one whole piece, so it is important to leave wearing ease and seam allowances from the start.
For a neat wrong side, the author uses a French-seam imitation and additionally finishes the edge on an overlocker.
Satin shorts with an elastic waistband
The result is the bottom part of a fashionable satin pajama set: short, loose shorts with a soft elastic waistband.
Materials and tools
Materials
Satin fabric, The amount depends on the size and shorts length; lay the fabric without skewing it.
Ready-made shorts pattern, 1 piece, The source uses a pattern approximately for size 40-42.
Elastic for the waistband, Choose the length by waist circumference with a comfortable fit.
Thread matching the fabric, For satin, use fine thread and test the stitch on a scrap.
Tools
Sewing machine, Before sewing, test the stitch on a piece of satin.
Overlocker or seam-finishing stitch, Not required, but helps make the wrong side neater.
Scissors, pins or clips, measuring tape, Clips are convenient for slippery satin if the fabric does not hold pins well.
Files and resources
Camisole from the same pajama setThe author split the set into two parts: the shorts are described here, and the camisole is in a separate master class.
Preparation
Check the fabric and size
Satin slips and shows stitching mistakes clearly, so check thread tension and pattern fit before cutting. If your size is larger than 40-42, decide in advance how much width to add.
Prepare the pattern
Print or redraw the shorts pattern. In the source it is one piece: one detail forms one leg.
Understand the result and pattern
First it is useful to see the finished set and understand how the shorts pattern works.
Look at the finished set
The finished shorts are sewn as part of a satin set with a camisole. This tutorial covers only the bottom half: loose shorts with an elastic waistband.
Finished result: a satin camisole and loose elastic-waist shorts.
The camisole is separate
If you need the full set, use the related camisole master class. This instruction keeps only the shorts so the steps do not get mixed.
Use the base pattern
The source pattern is approximately for size 40-42. It is one-piece: one piece is needed for one leg, so you will cut two pieces total.

Check the scale
Before cutting, place the pattern against yourself or against shorts that fit well to see whether extra ease is needed.
Enlarge the pattern if needed
If the base size is too small, the author suggests the simplest widening method: cut the pattern and add an insert.
Cut the pattern in half
Carefully divide the one-piece pattern vertically. This creates room for an even insert that will increase the width of the piece.

Add the needed width
Spread the pattern halves by as many centimeters as your size needs and secure the insert. For size 44 and larger, this added width is necessary: account for both wearing ease and seam allowances.
The pattern halves are spread apart to add the needed width.
Do not forget ease
Pajama shorts should not fit tightly. Satin is unforgiving when seams are under tension, so it is better to leave a little room.
Cut and assemble the shorts
After adjusting the pattern, move to the fabric: cut two pieces, sew the main edges, and prepare the waistband.
Cut two pieces
Transfer the pattern to the fabric and cut two identical pieces. Leave seam allowances along the edges and extra allowance at the top for later waistband finishing.

Tip from the discussion
If your sewing skills are still minimal, start with simpler fabrics first and move to slippery satin later. That way you can build confidence without spoiling beautiful fabric.
Sew the edges and prepare the waistband
Sew the main edges, leaving the lower hem and upper waistband line open. At the top, sew on a separate fabric strip: the elastic will be inserted into it.

Neat wrong side
For strength, the author imitated a French seam and also finished the edge on an overlocker. If you do not have an overlocker, use an available seam finish on your machine.
Finish and variations
Finish
Insert the elastic and check the fit
After assembling the waistband, insert the elastic, distribute the gathers evenly, and try on the shorts. The fit should be loose and comfortable.
Assemble the set
The shorts can be worn separately or with the satin camisole from the related master class. Together they make a complete lounge set.
Variations
Change the length
If you want a more covered model, lengthen the pattern at the hem before cutting and check the side seam line.
Try an easier fabric
For a first practice run, use a less slippery fabric and save satin for the final version.
After cutting or fitting, there is not enough width.
Likely cause
The pattern is for size 40-42, and the added width for a larger size or loose fit was too small.
How to fix it
Before cutting, cut the pattern and add an insert of the needed width. If the fabric is already cut, check whether you can reduce seam allowances or add side inserts.
Satin slips while sewing
Problem
The pieces shift and the stitching becomes uneven.
Likely cause
The slippery fabric does not hold well under the presser foot or was not fixed enough before stitching.
How to fix it
Fix the pieces more often with pins or clips, sew without pulling, and first test the machine settings on a scrap.
The edges look messy
Problem
Open or fraying edges remain on the wrong side.
Likely cause
The edges were not finished after sewing, or the fabric frays actively.
How to fix it
Use an overlocker, zigzag, or French-seam imitation. For satin, choose the finishing method on a test scrap first.
?FAQ
Is this master class suitable for a beginner?
Yes, if you already have the basic skill of sewing a straight seam. But satin is slippery, so for the first practice piece it is better to try a simple fabric.
What should I do if the pattern is smaller than my size?
Cut the pattern in half and add an insert of the needed width. For size 44 and larger, the author directly recommends leaving additional ease.
Can I sew without an overlocker?
Yes. An overlocker makes the edge neater, but you can replace it with a zigzag, another machine finish, or a French-seam imitation.
