Easy Baby Romper in 5 Steps ( Shortalls and Longalls)
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.

This is a romper pattern suitable for all seasons. You can make it as shortalls for summer or as longalls to be paired with a full sleeve tee- shirt for the colder months.

This romper sewing pattern comes with shoulder buttons for closure and as such, it is very easy on and off. That makes it the perfect choice when you plan to sew for a baby.

This free baby romper sewing pattern is very easy to experiment with and customize. You can cut solid colors from one piece and cut the other piece from coordinating printed fabric to make stylish rompers that look like store-bought ones.

Look at the above baby rompers as shortalls and longalls, I made matching ruffled bonnets too! Doesn’t the pair look like perfect gifts for new moms?
Try out this free romper pattern; it is simple and fun. It is also one of the few baby sewing projects that’s so easy that even a beginner seamstress may complete it with satisfying results.

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
Thank you for sharing your patterns. They are so cute and I hope to make one of them this next week.
Can this romper be made with knit fabrics? Thanks
Thi pattern is designed for wovens only.
Can fleece be used for romper? Thanks
The pattern is designed for wovens but since fleece is a moderately thick fabric, it should be okay!
