So the Criss -Cross dress tutorial is one of my all-time most popular posts ever, and it occurred to me, as a boy mama, that I don’t have an equivalent for boys. What was I thinking? So today I’m sharing a free pdf sewing pattern for a basic romper, the type I used to make Bean when he was a baby.
This was him at 1 year old – I don’t have pictures of him in these younger than that, though I did make them. The one I’m sharing today is a 0-3M size, so smaller than the one you see Bean wearing in these pictures.

- The pattern
To sew this, you can use the video tutorial below, which you can also watch here, or scroll past it for written instructions.
After printing and taping the pattern, cut out your pieces according to the directions on the pattern. Mark buttonholes on the right side of the back piece.
Sew the front to the front lining along the armhole and neckline, right sides together, using a 1/2″ (12mm) seam. Repeat with the back and back lining. Clip the corners and curves.
Turn front and back pieces right sides out and press.
Sew the buttonholes on the back piece.
Place the front on top of the back, lining sides together. Open the side seams and pin the front to the back and the front lining to the back lining at the side seams, matching the armhole seam. Sew each side in one seam.
When you fold the front and back down, the seams are enclosed inside.
Sew the shorts fronts along the curved crotch seam, right sides together. Repeat with the shorts backs. Finish this seam with your preferred seam finishing method (seam finishing tutorial here).
Open up your shorts front and back and place them right sides together. Line up side edges and sew, then finish with your preferred method.
Lay your shorts flat so that the side seam is facing up. Press the bottom edge up 1/4″ (6mm) twice, then stitch in place to hem. Repeat on other leg.
See the short raw edges on the bottom right and left of this picture? Those are your inseams, and we will be looking at them more closely in the next picture.
Lay shorts so crotch seam is facing up. Iron a piece of 1/2″ (12mm) wide interfacing onto the shorts 1/8″ (3mm) away from the raw edge of the inseam. Trim interfacing to fit the width of the inseam.
Iron the 1/8″ (3mm) or raw fabric toward the interfacing.
Fold the inseam again 1/2″ (12mm) to cover the interfacing. You will have to stretch fabric on the bias to achieve this. Make sure the center seam on the folded edge aligns with the center seam of the shorts, then stretch the folded fabric toward the hemmed edges. Stitch folded edge in place. Repeat with other inseam, making sure the two inseams are the same length.
Turn the shorts right side out. Pin the outside of the top only (not the lining) to the shorts at the waistline, right sides together. Match top front to the shorts front, the top back to the shorts back, and make sure to match the side seams. Stitch around waistline.
Turn romper wrong side out. Press the seam from the previous step up toward the top. Then fold the bottom edge of the lining under 3/8″ (9mm) and pin over the seam. On the right side of the romper, stitch in the ditch of the waistline seam to secure the lining in place. Alternately, you could handstitch the lining to the seam allowance.
Set 3 snaps on the inseam. One should be just to the side of the center seam, the other two close to the edges.
Tip: use an old thread spool to keep the snap intact while you hammer it on.
Sew the buttons on the shoulders, and there’s your finished romper for a new baby boy!
Or, you know, on an older baby, since I can’t find any pictures of Bean wearing these when he was tiny! Of course, these pictures still look tiny to me compared to the big 3 year old he is now!
