Baby Romper Sewing Instructions & Tutorial
This project has a lot of steps but it really sin’t super time consuming to sew so don’t panic 🙂 Use a 1/4″ seam allowance unless otherwise noted
Baby Romper Pattern Step 1: Add a 1″ strip of interfacing to each front romper piece 1/4″ in from the placket edge. Your placket is the portion up at the top. Finish the center front seam/bottom edge of the placket with a serger or zig-zag stitch. While you have your interfacing out add a piece of interfacing to the front snap placket, 1 back snap placket and 1 collar piece. 
Baby Romper Pattern Step 2: Fold each side of the placket over 1/4″ and then another 1″ towards the wrong side of the romper and press flat. DO NOT SEW
Baby Romper Pattern Step 3: Press the bottom edge of each sleeve up 1/4″ and then another 1/2″ and press flat. DO NOT SEW
Baby Romper Pattern Step 4: Press the top edge of the pocket over 1/4″ towards the wrong side. Press the top edge over 1/2″ towards the right side and topstitch the folds in place 1/2″ in from the sides. Turn the top of the pocket right side out and press the sides and bottom edges in 1/2″. Topstitch the top of the pocket.
Baby Romper Pattern Step 5: Topstitch the pocket to the left shirt front along the sides and bottom edges
Baby Romper Pattern Step 6: With right sides together (RST) sew the 2 back pieces together along the center back seam/back rise. If you’d like you can topstitch the seam allowance to either side of the back piece.
Baby Romper Pattern Step 7: With RST sew the 2 back placket pieces together along the outside and bottom edges using a 1/4″ seam allowance. Trim your seam allowance, turn right side out and press flat
Baby Romper Pattern Step 8: With the back placket on the right side of the fabric sew the raw edge of the placket to the back inseam using a 1/4″ seam allowance. The placket will end 3/4″ before the raw edge of the romper (this leaves room for the hem).
Baby Romper Pattern Step 9: With RST sew the collar pieces together using a 1/4″ seam allowance along the 2 sides and outside edge. Trim the seam allowance, turn right side out, press flat and topstitch
Baby Romper Pattern Step 10: With RST sew the left and right front pieces to the back at the shoulder seams. If you’d like you can topstitch this seam allowance to the front of the romper. 
Baby Romper Pattern Step 11: Center the collar on the neckline and sew in place with a 1/4″ seam allowance. Your placket should be unfolded during this next series of steps. 
Baby Romper Pattern Step 12: Fold the placket back along the pressed fold line from step 2. The collar will now be underneath the placket.
Baby Romper Pattern Step 13: Unfold your bias tape. With RST sew along the fold line in the bias tape right on top of your stitching line from step 11. Make a series of little snips into the seam allowance so it lays well in the next step.
Baby Romper Pattern Step 14: Flip the collar up and turn the front placket right side out. You will now have a beautifully finished corner for the top edge of the placket. Press flat. Bring the bias tape down so the seam from step 13 is covered and the topstitch is in place. Now is a great time to add a tag if you have one 🙂
Baby Romper Pattern Step 15: Line up the center front edge of the left and right front pieces and sew together using a 1/4″ seam allowance. Go straight up and stop 1/2″ past the start of the placket. Do not turn and sew any portion of the placket
Baby Romper Pattern Step 16: Refold the placket pieces and press flat. Topstitch each side of the placket (you will need to move things out of the way a bit as you sew). On the left front piece (or right if you’re sewing for a girl) add a line of topstitching along the center front edge.
Baby Romper Pattern Step 17: Overlap the placket pieces so everything is laying flat. Starting at the crotch topstitch along the center front seam up to where you left off in the previous step. Sew over to the far stitching line, turn and go down 1/2″ and then back to the center front line to secure the bottom edges of the placket pieces.
Baby Romper Pattern Step 18: Add snaps or buttons to the front placket. If you are using buttons do a horizontal buttonhole for the top button instead of vertical
Baby Romper Pattern Step 19: Finish the outside edge of the front snap placket piece
Baby Romper Pattern Step 20: With RST sew the front snap placket piece to the front romper using a 1/4″ seam allowance. It will end before the bottom edge of the romper. Keep in mind that your “center front” seam is actually off to one side by 1/2″. Clip along your seam allowance. Flip to the inside of the romper and topstitch in place along the seam and along the outside edge to keep it in place.
Baby Romper Pattern Step 21: With RST sew the sleeves into the armholes. If you want you can topstitch the seam allowance to the body of the romper.
Baby Romper Pattern Step 22: With RST sew up the sleeve inseam and romper side seam. You will need to unfold the sleeve hem while you sew this step.
Baby Romper Pattern Step 23: Refold the pressed lines of your sleeve and hem.
Baby Romper Pattern Step 24: Fold the bottom edge of the romper up 1/4″ and then another 1/2″ and topstitch to hem. 
Baby Romper Pattern Step 25: If you want you can also topstitch the seam allowance of the back facing to the romper
Baby Romper Pattern Step 26: Add your snaps and you’re done!

Nice and cute handwork romper. Thanks for sharing!
Is the back crotch placket a separate piece sewed on to back? I’m confused how to attach. I understand the front placket being stitched RST then flipping back to inside. Thanks for any help
Wow, you have magic hands.
Wow, I do not think I can make it.
Can you please send a new link for the free tutorial on the pattycake boy romper? I clicked on the link and it is no longer available.
Thanks

Great share! I’m eager to get my hands dirty and try it out now.
Great share! I’m eager to get my hands dirty and try it out now.
Made the free version and it turned pretty good. Definitely not a beginner pattern. Maybe confident beginner… My first collar, button placket, sleeves, and crotch snappy thing. I think I need a serger; cover stitching all those little curves almost undid me lol. But i love how it turned out.
downloaded this pattern but there is no fabric layout attached can anyone help me please
This is so very cute. I sew for Preemies of the Carolinas. I wonder if there is a pattern for preemies. If not can you tell me how to make it smaller?
Hello,
My english is very far away now, so, scuse me;
I’m doing this pretty romper for a 5 months old, baby. I wander if the seams allowance are in the pattern or if i have tu cut a larger with 1/2″;
thank you for your reply
from France XXX
the seal allowance is included in the pattern
Chantal, au secours! mon anglais est encore plus loin que le vôtre… Que signifie 1/4″, 1/2″, po et RST. Je n’ai pas compris et je suis bloquée. Cordialement de France aussi.
Les mesures sont en pouces, chaque pouce mesure environ 2,5 centimètres. RST signifie que vous devez placer les tissus à droite contre droite. Salutations du Venezuela.
Love them so much. lol Babies would be cuter when they wear these button-up baby rompers.
This is super cute..is there a video for this? Im a beginner would love to try to make this but would do way better if I could see it being made. Thanks for sharing..its adorable
I would love to sew your free romper pattern for my grandson. It looks lovely.
Do you think I could make this into a shirt? I have enough fabric to make just the romper part without the sleeves or collar. I don’t want to use other fabric (it’s for my son’s baptism outfit) so it seems a little casual to use other fabric for sleeves/collar. I can’t buy more fabric. Do you think it would be too boxy to just cut it off around the waist?
Can I use buttons on the crotch as I don’t have snaps or access to any?
You could use buttons. You can also buy snap tape. It is like a ribbon that already has the snaps attached to it.
Finished! I’m an experienced quilter, but new to patterns, so this was a challenge for me. Thank you SO much for the detailed instructions and color photos. I never would have made it through without. This is for my grandson, made from an upcycled shirt from his Grandpa. Turned out so cute! Thank you for the excellent pattern.
Is this no longer free? Or am I missing a code? 🙂

Is there a way to print the tutorial for the baby romper. I have downloaded an printed the pattern.
You could copy it over to a word document and then print
I bought this green anchor print fabric at my local fabric store and I am currently making one of these rompers for myself. I simply adjusted the zoom in my Adobe Reader to around 140% and traced the lines onto a piece of large craft paper for use at home. The print settings still showed the original pages but were cut off because the pattern went outside the “print area” so I simply traced it for my own personal use instead of goofing around with my printing. Some family is coming down and they have two girls who are about 10 and 15 and I figured that the youngest would still be playing outside at parks and on school playgrounds. With this in mind, I want to be dressed for these outside trips and I figured that a simple ons piece would do the trick for being outside with my family.
I’d love to see a photo when you’re finished 🙂
What type of fabric did you use? Cotton or a knit?
Cotton but knit will work too
Love, love, love it!! So freakin adorable…and love working with those snaps
Could I ask what size snaps you used? I have a bunch of size 20 left over from my diaper making days and was thinking about using them if they weren’t too big.
Thanks Linda
I’m pretty sure that’s what I used 🙂
