I’ve been looking at how to make a custom overalls pattern, based on drafting techniques, which I began with this post: Drafting Shortalls from Scratch. But how to construct them? Well, that’s what I plan to explore today! To do this, yesterday, I cut out another pair of overalls, this time for the fall-winter-spring season, to retrace my steps.
Step One
With your pieces cut out according to your measurements, you should have four leg pieces – two front and two back. The next two bib pieces should be cut out, with the back piece cut a bit differently to accommodate the straps. This is to anchor the straps at the middle of your shoulders to keep the overalls securely on your frame.

Step Two
I like to begin with the pants or shorts portion of an overall project, because they are foundational to the silhouette. I like to pin the leg pieces together to try on before sewing. Remember to leave several inches of the outer thigh seams pinned for the flies and buttons.
Once you know that the pieces will fit, with seam allowance accounted for, I begin sewing the leg pieces together, leaving out the crotch seam and the top part of the inseam, to attach the two pieces as one pair of pants. After these have been sewn together and I have tried them on, I will move on to the bib.
Step Three
For less bulk, I like to cut the seams of the crotch portion and leg seams that will join together, with pinking shears, to make my hems less thick. This lets the sewing machine, or your hand sewing needle, pass through the seam with ease, and is more comfortable to wear.
How do you join pants? Well, you leave the top of the inseam open so that those two inseams will line up together, making the two legs join at the top where the pelvis is. Remember this is a bifurcated garment, so you want your final shape to be two tubes, joined to make one tube at the top. I’ve messed this up several times; it’s okay even if you sew it wrong the first thousand times. That is what mockups and seam rippers are for!

Step Four
For the bib of these overalls pictured above, they were cut into short pieces, so I just had to join these pieces together. I added a facing to the inside of the bibs, which is just a piece of the fabric’s right side facing inside, so that the bibs are finished cleaner around the neckline.
I inserted the straps between the facing and the bib for a clean and secure stitch. The straps were finished with a loop on either side of the front bib to tie around, instead of the metal fastenings. I was inspired by Lucy and Yak Dungarees.
Step Five
The final touches are the bias tape, the side buttons, and the five pockets. I find the bias tape the most mundane thing; therefore, I choose to do that next, which is a 1-2″ ribbon of the fabric used to finish the raw edges still exposed on the sides.
Step Six
Next, I created the flies on either side by folding over the fabric to make the button placket and button hole placket. This was planned out when I cut out the overalls. After making the button holes and finishing them with either the machine or by hand, I mark out on the other side where the holes overlap to mark for buttons.
Step Seven
Finally, I sew the pockets. I chose a large, half-rounded bib pocket on the front, two smaller rectangle pockets on the backside, and medium side pockets sewn across the hip. Next? Enjoy your creation and feel a sense of accomplishment. You did something hard, and probably felt lost at times, but you persevered to learn a new skill. It’s not cringeworthy to try. So go for it! ❤
