How to Serge a Onesie Dress that Stretches at the Waist

Posted on October 26, 2021October 26, 2021 by jghuiz

Surfing the internet one day, I stumbled across a photo of a cute little girl’s dress that reminded me of candy corn. Right then I knew my baby granddaughter needed her own version of that dress. Instead of a regular dress though, it needed to be a onesie dress. Onesies are the perfect base for a baby dress or shirt because they stay tucked in and don’t ride up and expose little belly buttons! And of course, I had to use my serger to make it. After a little experimentation I figured out how to serge a onesie dress that stretches at the waist. This blog post is a summary of my process. In the future I plan to create more detailed instructions for this style onesie dress using several different serger techniques. So stay tuned!

The Typical T-Shirt or Onesie Dress

There are many great tutorials on the internet for making cute onesie and t-shirt dresses. The typical method for creating a onesie or t-shirt dress is based on gathering a piece of cotton fabric with long basting stitches and then stitching the gathered fabric to the t-shirt or onesie. I’ve made t-shirt dresses like this before, but I’ve found that the woven fabric skirt limits the stretch of the waist seam. In the previous dresses I’ve made, the waist seam stretches very little or not at all. If the t-shirt is loose and baggy there is usually enough wiggle room to get the dress on a child without popping seams, even if the seam doesn’t stretch. But with a close fitting onesie, it’s really difficult to get it on a baby if the fabric at the waist doesn’t stretch.

How to Serge a Onesie Dress that Stretches at the Waist

To create my candy corn skirted onesie I wanted to use a couple of cute woven cotton polka dot prints. So I had to figure out a way to add a skirt to my onesie without losing the stretch around the waist. I decided the best way for me to do this was to use my serger, along with an elastic foot to gather the top edge of the skirt using elastic.

I also used a ruffling foot to simultaneously gather and attach the bottom ruffle to the skirt.

The ruffling foot and elastic foot are presser feet that help you gather fabric or attach elastic to fabric. You can gather fabric or attach elastic to fabric using a serger without these specialty feet. The feet just make the process quicker and more professional looking.

Supplies

Baby onesie – I used size 6 month long sleeved by Carters
4½” x 45” wide cotton print fabric for main skirt
Two – 2½” x 45” wide strips of cotton print fabric for bottom ruffle
⅜” wide elastic – 2X the width of the onesie (where you will attach the skirt) plus 6”
Serger thread for overlock and rolled hem stitches
Optional – 1” thin fusible knit knit stay tape – 2 x the width of the onesie (it helps to stabilize the onesie where you cut it so the edges don’t stretch out as you handle/serge)

Supply Notes

Since I added a seam at the waist, the onesie did get a little shorter (about ½-¾” shorter). Keep this in mind when selecting your onesie. You may need to select a onesie that is a little bit longer than the length you actually need.

I made the skirt on the onesie shorter so the onesie looked more like a skirted shirt than a dress. I wanted more of a shirt that she could wear with pants. Feel free to make your skirts any length you desire.

Tools

Serger capable of 4 thread overlock and 3 thread rolled hem
Elastic foot for serger – helpful, but not required
Ruffling/gathering foot for serger – helpful, but not required
Serger accessories and manual
General sewing supplies
Sewing machine for basting (optional)

Summary of Steps

The steps below are a summary of the steps I took to make my “Candy Corn Skirted Onesie” for the blog post “How to Serge a Onesie Dress that Stretches at the Waist.” This style onesie consists of cutting apart the onesie and inserting a gathered skirt.

Step 1: Seam the Bottom Ruffle

I used a narrow three thread overlock stitch to seam my two bottom ruffle pieces together into one long strip.

Step 2: Finish Bottom Edge of Ruffle

Next I used a three thread rolled hem stitch on my serger to finish the bottom edge of my long ruffle strip.

Step 3: Gather Bottom Ruffle and Attach to Main Skirt

I simultaneously gathered my bottom ruffle and attached it to the main skirt piece using the ruffling foot for my serger.

Step 4: Gather Top Edge of Skirt Using Elastic

I used my elastic foot and elastic to gather the top edge of the skirt fabric. There are many variables that determine how much fabric will be gathered to the elastic using an elastic foot – things such as the type of fabric, the type of elastic, how the fabric is guided into the foot, etc. Because of these variables I factored in a some wiggle room and used a little more fabric than I actually needed for the skirt. Because I could easily cut it to size in a future step (step 6). It’s much harder to add fabric than to take it away!

Step 5: Prepare Onesie

I measured down 1” from the armpits and marked a line across the front and back of the onesie. I also added a fusible knit stay tape over the cutting line to add stability to the future cut edges at the waist. Then I cut the onesie apart at the line.

Step 6: Prepare Skirt for Attaching

I measured the cut edge of my onesie and cut my elastic gathered skirt piece to match (2X this measurement plus 3/4” for seam allowances.)

I serged the short edges of the skirt seam together using a standard four thread overlock stitch.

Step 7: Insert Skirt and Serge Waist Seam

I placed the wrong side of the skirt against the right side of the bottom half of the onesie, lining up the raw edges. Using my sewing machine, I basted the skirt to the onesie bottom.

Then I placed the right side of the top half of the onesie against the right side of the skirt, lining up the raw edges of all three pieces (the top half of the onesie, the skirt, the bottom half of the onesie.)

Next, using a standard four thread overlock stitch, I serged all the way around the waist seam.

And that is how I created a fun and functional serger onesie dress that stretches at the waist. But I wasn’t quite done yet. There were a few more things I needed to do.

Step 8 – Make a Matching Hair Bow

I took the scraps of fabric leftover from the skirt and made a matching hair bow.

Step 9 – Find a Model and Take Photographs

Isn’t my model cute?!!! I call her my Candy Corn Cutie. The candy corn skirted onesie is the perfect outfit for my granddaughter to wear this October!

Serger Funsie Onesie

Posted on June 30, 2020June 30, 2020 by jghuiz

Transform an ordinary onesie into a super sweet outfit for a little baby girl! This Serger Funsie Onesie is fun to create using basic stitches on your serger. My niece is having a little baby girl and her nursery theme is owls. I found this cute little owl onesie and knew I could turn it into something special. I can’t wait until the baby is big enough to wear it!

The Funsie Onesie Pattern

The pattern for the Funsie Onesie came from the book, Simple Serging Sewing, edited by Julie Johnson.

The Transformation from Onesie to Sweet Dress

I was amazed at how a few simple additions took this onesie from cute to amazing! Read along and observe the transformation.

Here’s my onesie, skirt fabric and waistband bias strip.

Prepare Strip for Ruffled Skirt

Because my onesie was larger than the one in the pattern, I added 1” to the length of the ruffled skirt piece.

The instructions said to use a plate as a template for rounding the ends of the ruffle strip. I used the plate as a starting point, and then I drew in the rest of the curve in freehand.

For this project I used a Babylock Imagine serger. I set my serger up for a 3 thread narrow hem to finish the bottom edge of my ruffled skirt. You could also use a 3 thread rolled hem if you like. I used Maxilock thread in a color that matched my fabric.

For helpful information on serging with a rolled hem, check out my tutorial on Quick and Easy Serger Napkins. https://overtheedge.blog/tutorials/quick-easy-serger-napkins/

Gather Skirt

To gather the ruffled skirt, I used my serger ruffling foot (the G foot for the Babylock Imagine) with a 4 thread overlock stitch. Even though you can use the foot to simultaneously create the ruffle and attach it, I chose to do it in two steps so I could adjust the ruffle to fit the onesie exactly. I set my differential feed to 2, my stitch length to 4 and my stitch width to M. The raw edge of the skirt was just skimmed by the blade as I serged. I also held my finger behind the foot to help it gather just a little bit more.

If you don’t have a ruffling foot for your serger, you can still use your serger to gather. Follow your instruction manual for gathering. Usually gathering on a serger involves increasing the differential feed and stitch length (and increasing your needle tensions if you have a serger with tension dials.)

Here’s what my ruffled skirt piece looked like after gathering it with my serger.

Prepare Onesie

Determine where to cut your onesie. My onesie was a 6-9 month size. I cut it apart as stated in the pattern instructions.

Create Bias Waistband

Next I created the bias waistband strip. The bias fabric strip has a some stretch which makes it a little easier to dress the baby. The waistband also adds back in length that was lost in the seams from adding the skirt to the onesie. So your onesie length will still be the same size as when you started. I used a standard 4 thread overlock stitch with a stitch length of 2.5 to serge the ends of the waistband together.

Attach Waistband

I pinned the bias waistband strip to the top half of the onesie, and serged the seam with a standard 4 thread overlock stitch.

Attach Skirt

My onesie waistband measured about 18” around, so I adjusted the gathers of my ruffle to equal 20” (18″ + 2″ for overlap.) My serger didn’t gather the fabric quite as much as I needed. So I adjusted the gathers by first separating the needle threads from the looper threads. And then I pulled on the needle threads and slid the fabric, just like I would using 2 rows of basting stitches on my sewing machine. I overlapped the ends of my ruffled skirt by 1” on each end.

After adjusting the gathers, I pinned the ruffled skirt to the bottom of waistband, aligning the overlapped section of skirt slightly off center. I serged this skirt to the waistband using a standard 4 thread overlock with a stitch length of 2.5.

Attach Bottom Half to Top Half

After attaching the skirt, the last step was to reattach the bottom half of the onesie. I pinned the onesie panties to the waistband/skirt section, making sure that the side seams of both onesie halves were aligned. To serge this seam, I increased my stitch width as wide as it would go (7.5) and used a stitch length of 2.5. I made this stitch wider than the stitching I used to gather the ruffle, so the gathering stitches on the skirt would not show on the right side of the garment.

Add Finishing Touches

Even though the skirted onesie was adorable, I thought it needed just a little something more. So I hand stitched a few ribbon roses on the waistband and one at the center of the neckline.
