Do you want to sew a dress without complicated patterns or hassle? With a good t-shirt pattern, you can make a dress in no time that fits perfectly right away. I often use free t-shirt patterns for this. By simply adding a skirt section, you can turn a simple shirt into a complete outfit.
Free t-shirt patterns that work perfectly
These are the free sewing patterns I like to use myself. They all have a slightly different fit and look:
- Threads by Caroline – Ester & Ebbe (free when signing up for the newsletter)
- Brindille & Twig – Ringer Tee
- Misusu Patterns – Rowan Tee
Tip: choose a pattern you have made before. That way, you know for sure the fit is right.
How do you turn a t-shirt pattern into a dress?
The principle is simple: you make the shirt shorter and add a skirt section to it.
Step 1: Determine where the skirt starts
Take a tape measure and measure from the shoulder:
- To where the skirt should start (e.g., navel or hip)
- To where the dress should end (e.g., just above the knee)
Example:
- From shoulder to navel: 35 cm
- From shoulder to knee: 64 cm
Step 2: Adjust the shirt pattern
You only use the top part of the shirt. Check carefully if the pattern already includes seam allowance. In my example, the length of the pattern should be:
35 + 1cm shoulder seam allowance + 1cm skirt attachment seam allowance = 37 cm
Fold away the rest of the pattern so that you can still use it as a shirt later. Ensure that the front and back pieces are the same length; you can check this by laying the pattern pieces at the armhole on top of each other.
Step 3: Calculate the skirt section
The skirt section is a simple rectangle that you will gather. Calculate the length of the skirt as follows:
Total length – top piece = skirt section
In my example:
64 cm total - 35 cm top piece = 29 cm skirt
You still need to add the seam allowance and hem to this. I like to use a 3cm hem for French Terry and Jersey.
Using my example:
29 cm skirt + 1 cm attachment seam allowance + 3cm hem = 33cm high
Now determine the width of the skirt section; this determines how full the dress will be:
For French Terry: pattern width × 1.7
For Jersey or rib knit: pattern width × 2
Example: Shirt width is 40 cm and I am working with French Terry.
40 × 1.7 = 68 cm
The total skirt section then becomes 👉 68 cm wide × 33 cm high
Cut this 2 times (front and back).
Step 4: Assembly
- First, sew the shirt part following the instructions of the pattern you are using.
- Gather the skirt sections
- Attach the skirt to the shirt
- Finish with a hem
- Done! Your dress is finished.
My version of this dress
For this dress, I chose a French Terry fabric, because it has a slightly firmer structure and gives a tougher look. I had the skirt start at navel height and end just above the knee. This way, it can be worn throughout the entire spring and summer.

Which fabric do you choose?
The fabric largely determines how your dress looks:
- French Terry fabric → slightly firmer, tougher, less flowy
- Jersey and rib knit fabric → supple and airy, hangs looser
By combining fabrics cleverly, you immediately get a complete outfit that works.
Why this works so well
- You use a pattern that already fits
- You don't need to learn anything new
- It's finished quickly
- The fabric makes the difference. This is ideal for all those cool printed fabrics.
Frequently Asked Questions:
Can you make a dress out of any t-shirt pattern?
Yes, as long as the fit is good, you can extend almost any t-shirt pattern with a skirt.
Which fabric is most suitable?
For a tougher dress, choose French Terry. For a supple-hanging dress, jersey or rib knit is better.
How much fabric do you need?
On average between 0.8 and 1.5 meters, depending on size and length.
