Turn a Men’s Shirt into a Baby Romper with a Free Sewing Pattern

Learn how to upcycle a men’s shirt into a baby romper with this free 6 mos sewing pattern. This intermediate sewing project is so cute for babies to wear!

I have really, really loved making boy clothing. Everytime I make something new or am inspired by something, I am grateful I have a boy and get to experiment with his clothing.

Well, I was first inspired by this shirt romper. I thought I would make it from scratch, but I knew I could easily make something similar by using parts of a man’s button up shirt. Today I have a pattern and tutorial to share!

If you use a lightweight shirt, it’s perfect for the hot summer months, and the front buttons or snaps are functional because you use the original shirt front button placket.

Button up shirts are one of my favorite things to refashion. There’s so much fabric, and so many possibilities! Look at all these button up shirt refashion tutorials!

What is a PDF sewing pattern?

A PDF pattern is a sewing pattern designed on the computer and organized so that it can be printed on several letter or A4 size pieces of paper.

I love using PDF sewing patterns because if the pattern gets ruined or if my children or I changed sizes, I can always print it again. It’ll never be destroyed since I have a digital version!

How do you use a PDF sewing pattern?

Open the PDF on a computer and click print. When printing make sure that the scaling is set to 100% or no scaling so that the pattern prints at the correct size.

Once the pattern is printed it can be taped together to get the full size. Then the pattern can be cut for each pattern piece size or individual sizes can be traced so that the pattern can be used again and again.

Cutting

Unbutton the front of the men’s shirt. Line up the plackets and smooth out the rest of the shirt as you can. Cut out the mirrored front body pattern pieces from the front of the shirt. Line up the center front line of the body piece with the line of buttons and buttonholes. Use the button guides so that you don’t cut through a button or buttonhole. There’s a chance that you will be cutting through the pocket especially with the smaller sizes.

Fold the back of the shirt in half along the center back. Lay the back body pattern pieces below the yoke along the fold and cut them out.

Lay out the yoke pattern piece along the center back fold of the original yoke and cut out two pieces. When you cut from the back yoke you will automatically cut two yokes at one time.

Fold the sleeves along the top sleeve fold line and place the sleeve pattern pieces along the fold. Cut out one sleeve from each sleeve.

Open the collar and stand up to lay down flat. Place the collar pattern piece on top. Try lining up the seam of the collar and stand with the indent of the collar pattern piece. Cut out two collar pieces. Leave the interfacing attached. When you cut from the collar you will automatically cut two collars at one time. If the collar is too small for the pattern piece, then cut two collar pieces from any fabric left from the shirt.

Cut out the inseam facing pattern pieces from whatever fabric is leftover. If you don’t have enough, you can use some lightweight cotton fabric (like quilting cotton) in a coordinating color.

Cut the gusset from a scrap of the shirt. Match up the grainline of the shirt with the grainline of the pattern.

Sewing

Match up one center back notch of the back body pattern pieces and one notch of the gusset with right sides together. Match up the two sides. Sew the seam and finish the raw edges.

Place the two front body pieces right side down onto the right side of the back. Fold the back yoke down and away from the shoulders.

Roll up the body front and the body back pieces into a tiny roll until you can sew both yokes. Bring the lower yoke from the bottom and up over the roll until all the shoulder seams are matching.

Pull the body roll out of the yokes through the neck hole.

Sew the pieces together but do not sew through the collar seam on each side.

Press the seam allowance and collar up away from the body.

Fold the edge with the 3/8 inch stitching guide under and pin to the neckline so that all of the collar is enclosed.

Edgestitch along the neckline and around the collar to keep the edges nice and to close the hole.

Interface the front inseam facing. Finish the outer curve. Interface one of the back inseam facings.

Place the back inseam facings right sides together. Sew the bottom straight edges and the outer curve.
