Step 1: Materials
Sewing Machine (you could do hand sewing if you don't have one currently)
Dress Form or someone to help you pin
Seam Ripper (I just cut the seams out)
Step 2: Cut Off the Legs
Depending on the size of your sweatpants, you could simply hem the bottom and stop here. I preferred a longer skirt so I continued on with the transformation.
If there are any holes in the fabric patch them using a straight stich. This is the easiest method, and the line that was created will be covered up with the pockets.
Step 3: Pockets!
I created the pockets from the leftover material in the legs. Roll down the top and the bottom of the pockets and top stitch. Although this isn’t required when working with knits since they don’t fray, I think that it gives a more professional feel. You could also use a contrasting thread to make the topstitching stand out. I used matching because my top stitching (like my cutting) isn’t perfectly straight.
I decided to flip the skirt so that the original waist was the new hem since it was so large.
The pockets will be placed on opposite panels of the skirt. Pin them and baste (a long stitch used to hold things in place while the garment is being constructed) the skirt back together. Don't worry about fit in this step, it will be adjusted next.
Finally, top stitch the bottom of the pockets and part of the top. Make sure that you can still fit your hand in them!
Step 4: Adjust to Fit
Step 5: Add the Waist
Fold the circle in half so that the pretty sides of the fabric are facing out. Baste stitch the bottom (this makes attaching the waist to the skirt much easier)
To attach the waist to the skirt, pin the waist to the outside of the skirt so that the edges align. Sew with a zigzag stitch to finish. This may require some pulling because they may not be the same size. If there is too much of a difference (there shouldn’t be since they were both sized to your waist prior to sewing them) adjust the skirt seams to fit.
Now you have a new skirt perfect for summer! It even has pockets!!
