Sharing is caring!

Here is another baby romper pattern from me, but this time for baby girls as well as baby boys. This is a very simple romper pattern that can be made from just two fabric pieces and in just 5 steps. In fact, this is one of the easiest of all the romper patterns.

Easy Baby Romper in 5 Steps


Materials Required:


  • Fabric for the overall body- you may use medium weight plain or printed cotton fabric, denim, or corduroys-requirement specified in the table-1 below.


  • Fabric for the facing- requirement specified in the table-1 below.


  • Ornamental buttons for the shoulders-2.


  • Sewing Notions.


  • Pattern Template.



All the fabrics used here are 44/ 45 inches wide.


The fabrics shown here are only for illustration purposes and as such may vary from the original.


The seam allowance is 3/8 -inch unless otherwise specified.


I suggest you read the entire pattern once before starting to get a general idea.


All seams are to be finished by zigzag or serger.

Take the fabric required for the overall and facing.


Step-1: Cutting The Pieces


Cut the template for the overall from the PDF. Keep the template on the right side of the fabric and mark around it. Cut along the marked line to get one of the pieces for the overall. Repeat the steps on the wrong side of the fabric to get one more of the same piece.


Your overall pieces would look like this (one is the mirror image of the other).


Next, we need to cut the facing for the overall. For that, we use the same template but we cut it short along the first glue line to make a shorter template.


Keep the template on the fabric and cut the facing pieces; again one on the right side and the other on the wrong side of the fabric. Your facing pieces would look like this.


Step-2: Sewing The Center Seams


Keep the two pieces of the overall layered, with the right sides together and aligning the edges all around. Sew along the two sides, starting from the lowest point on the neck to the crotch as shown above.


We move on to the facing pieces.


Take the two pieces for the facing and sew them together just as we did with the overall body pieces. Zigzag all around the lower edge of the facing to prevent fraying.


Step-3: Sewing The Overall and Facing Together


Turn the overall over to the right side and realign it such that the two seam lines fall in the middle, in line with each other. Similarly, place the facing with its wrong side out and slide the overall into the facing.


Align the neck and the armholes of the two pieces together and pin all around.


Sew around the pinned neck and armholes, removing the pins as you go. Now the overall body and facing pieces are sewn together.



Snip the edges to reduce the bulk in the seam.


Flip the facing over to its right side and push it into the wrong side of the dress. Poke out the edges using a mildly sharp object like the tip of a dowel or ruler (picture for illustration purpose).


Press the edges to make it neat and crisp.


Topstitch around the neck and armholes.


Step-4: Finishing The Lower Hem


Align the overall such that the seams come along the sides. Next, fold the lower edge of one of the legs twice by ½-inch and press. Repeat the steps on the other leg.


Sew the hem down on both legs.


Step-5: Finishing The Inseam.


Align the hemmed lower edges and also the inseams of the overall. Start sewing from one of the lower edges, up the inseam to the crotch, and down the other inseam till the other lower edge as marked above. Here again, reinforce the stitches at the start and finish.


Our overall is almost done, we need to do the buttonholes and sew the buttons.


Measure 1-inch from the curved edge of the backstrap and mark the line for the buttonhole, leaving equal space on both sides. Sew the buttonholes following the instructions on your sewing machine. Mark a point 1-inch below the front strap, leaving equal space on both sides. Hand-sew the buttons on both sides at the marked points. Note that you may adjust the position of the buttons and buttonholes after trying it on your child.


This is how it would look like when the straps are buttoned.

    Thank you so much…I have a few question…I used iron on interfacing because that’s what I had. With the sew interfacing does it just hang on the inside after you sew it to the armpit and neckline? Also when you say zigzag the seams do you zigzag both sides together or separate? I was taught to iron seams open so that’s where I get confused. Thank you Carolanne

      You are right, the interfacing would hang loose on the inside but don’t forget to topstitch the armholes and the neckline, as mentioned in the tutorial. You may zigzag the edges separately and sew the seams in order to press them flat!

      CarolAnne, the pattern calls for an outer fabric for the overalls and another fabric for a facing around the straps, neck and arm holes. This is different from interfacing. Facings are used to provide a way to make clean finished edges on parts that stick out, like the straps or areas which are at the edges of the garment like the neck line and arm holes, without requiring that the edges be turned and hemmed. Interfacing is generally used to provide extra stability and or thickness to certain areas of garments. Interfacing could be sewn in like a facing piece but most interfacing fabrics are not intended to be seen on a garment and some can be scratchy. Just saying.

    Thank you so much for the pattern. First one I did wrong. I used interfacing…just finished re making today. I love it! Both times the hem on the pant leg did not match up…Am I doing something wrong?

      The hems on the pant legs should match up if your sewing is right. But, if there is only a slight mismatch, you can cut and level it up.

    I re cut the pattern today. I had it on cardboard and wanted cleaner lines. I cut the pattern wrong last time ! I had put the pieces together after I cut them. I lined my glue lines with the make shorts line. I will remake them but not today! I think the other two I made will fit like half pant half shorts lol. Thank you so much! Oh my printer was not set to print color lines. Learning a lot!

    I’m just wondering if the pattern is supposed to be big. I measured the 2″ square and it is right but the pattern just looks so big to me. Am I doing something wrong. I print patterns a lot so I’m just a little confused as to why it is so big looking.

      You can check the finished inseam lengths and the torso lengths before starting to sew. The measurements are given in a table. The template ought to be big because it is a full-length romper!

    I made this for my baby cousin and its adorable! Thank you so much easy to follow along and not very hard to make. The pattern did look a little big at first and I had to shorten the length to fit but it turned out really good . I’m 14
