Free Romper Pattern {0-12 months}

Pattern and post updated 4/2015

Today I’m so excited to share this free romper pattern. Its my first pattern available in four  sizes!  0-3, 3-6 and 6-9 AND now 9-12 months.  This Romper has a front and back yoke, with gathered bubbble bottom. I used snaps to close the back and the diaper area. You can add optional ruffles on the front to make this outfit extra yummy.

This pattern is not my original design, I copied this romper from Oshkosh. It was a 6 moth size. The romper I made on the left is the smallest size of my pattern. I also sewed up the largest size, but forgot to get a photo of all three {and I gifted the small one!}


Okay… so go print the pattern and let’s get started.


1. I made the 6-9 month romper and it wasn’t very long. {new pattern has updated length included… you can always add length at dotted line on pattern.

2. you will need 3/4 of a yard fabric, 1/4″ Elastic and 6 snaps. I used KAM snaps, but regular set metal ones would work fine.

3. Seam allowance is included, but small 1/4-1/3 inch…

4. This pattern is intended for woven fabric, but if you know what you are doing, knits should work too.

Cut out the front yoke {x2} on the fold and back yoke {x4} and sew the shoulder seam to create two yokes.


Place the two right sides together and sew the neckline and arm holes. If you don’t use a serger, clip the seams now.romperpattern9

Pull the back yoke through the shoulder seam on both sides to turn the yoke and create clean seams. The front bottom and back bottom should still be un-sewn. Top-stitch the neckline and armholes close to the edge.


Fold back 1 inch of the left back yoke. Sew.


I have edited the bottom facing pattern piece. You can see the crossed out one on the pattern, ha! So I think its okay now, but if the facing doesn’t match the bottom of the romper, you can create your own by tracing the romper line and then cut a 3/4 inch wide semi-circle. Size guidelines are given on the facing piece, but place on the front piece, then trace.


Finish the longer edge of the facing, then sew the shorter edge to the romper bottom. Right sides together.


Top-stitch both sides of the facing to secure it to the romper. Front romper facing now complete.


Back romper facing. This should be four small pieces. Sew two together in the center, repeat with other two.romperpattern5

Place the two pieces right sides together, turn and top-stitch. The facing should now look like below.


Sew to right side of back romper.


Sew the side seams of the romper, right sides together. Measure the leg openings, and cut elastic 3 inches shorter than opening.


Sew elastic with a zig-zag and stretch the elastic as you sew. Fold elastic over and sew again to finish the leg openings.


Gather the top of the romper bottom. If you need tips for gathering – here’s a great gathering post} It should be 2 inches bigger than the width of the front and back. Pin the front, centering it between the side seams. Sew.


Pin the back {there should be 1 inch between the front and back yokes under the arms} Over lap the back yoke pieces by about 1 inch. Sew


You now have finished edges, except for under the arms.


Fold down and pin. Top stitch around the entire gathered top of romper, securing the under arms as you go. Put four snaps evenly placed in front and back bottom facing. Place two snaps on the back yoke as closure.


The finished back.

Cute right? The romper and the kids are pretty adorable if I do say so myself!


You can add ruffles to the front if you want.  I didn’t take step-by-step photos of the ruffles but here is the idea.

1. Cut fabric 1 inch x 24 inches. Cut 2 if thicker and 4 if thin {like mine.. I used chiffon}

2. finished the edge with a rolled hem. Mine were two layers, but if it was thicker use only one.

3. Gather down the center of the fabric strip. It should be 1 inch longer than the front of romper. Pin 1 ruffle right above front seam and sew down the center. Fold 1/2 inch around armhole. Sew the other ruffle right above the first, fold over ends the same way.
