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.

1. With right sides together, sew center back seam and side seams of the body pieces at 1/4″. Finish edges.

2. Take the collar pieces and with right sides together sew 1/4″ on all edges except the neck edge.
3. Trim the corns and turn right side out.
4. Poke out corners (I’m lazy and just use the tip of my scissors.)
5. Edgestitch around the sewn edge at 1/8″.

6. Take yoke pieces and sew center back seam at 1/4″.
7. Pin one yoke to the collar matching the center backs.
8. Let the he yoke should extend past the finished collar edge 1/2″.
9. Pin from the outer edges to the inside so if there is any excess, it will all be in the center. (The excess will be different depending if the yoke is cut on the bias.)
10. Resew center back seam of the yoke taking out the excess fabric.
11. Trim seam allowances of the center back yoke.

12. Take in the same amount you took in on the other yoke piece.
13. Flip collar over and pin the other yoke to the collar’s other side.
14. Pin so all three layers are together.
15. Sew straight across at 1/4″.

16. To finish the front edges of the yoke, turn inside out and sew across the edge at 1/4″. Don’t catch the collar underneath.
17. Trim corners and turn right side out.
* I wanted my yoke to extend out a little bit, that’s why I sewed mine at 1/4″. If you don’t want yours to extend then sew at 1/2″ or 3/4″.

18. When turned right side out, pin the two yoke layers together. There will be three straight edges, the two fronts and the back.
19. With right sides together sew each front straight edge to the top front of the body pieces at 1/4″. Sew the back straight edge to the top of the top of the back body piece at 1/4″. Finish edges.
20. Topstitch the seam allowances up towards to collar so it copies a man’s shirt yoke.

  1. Thanks for sharing, this is so great! Do you happen to have larger versions of the pictures? They don't get bigger when I click them and I'm struggling a bit on the yoke/collar piece.

  2. Hi! Thank you so much for such a great tutorial and pattern. Is there any way to size it up for a size 3T? What if I didn't actually use a Men's shirt and used fabric instead so that size of the original shirt wouldn't be a problem?

    1. You would just need to add width and height to all the body pieces. You would be fine using regular fabric as long as you added hem allowance and button placket allowance on the front.

  3. Heather, I apologize for my previous comment. It seems my printing issue may have been browser related. I tried it in chrome and IE and adjusted some of the page set-up settings. I was able to print something that looks more correct, so I'll try it and hope the end result isn't doll-sized. I'm really excited for this as I have SO many old dress shirts I don't know what to do with. Thanks again.

  4. This is exactly what I was looking for! When I click on the pattern link, it opens in another webpage tab. When I tried to print at no scale so it wouldn't shrink the images, it cut off some of the pattern pieces and didn't seem to print correctly. Any suggestions as to how to print? I typically use firefox, but I also have chrome or Internet Explorer I could use. Also, do you have any pattern measurement reference so I can be sure it printed correctly? I'd love to try this!

  5. I would love to print and use the pattern. However, when I click on the link, it opens in a webpage and doesn't seem to print the entire pattern pieces. I selected no scale so it wouldn't shrink the pieces. Any suggestions? Also, do you have a scale reference so I can make sure it prints the correct size? Thanks!

  6. When I print the pattern, I can't make sense of how Body Back A and Body Back B line up…they are different sizes and the sides don't match up no matter which way I turn them. Can you post a photo of what the back pattern pieces should look like when joined?

    Posted on September 8, 2013 at 1:58 pm
    1. The center back of Back A and the center back of Back B should line up. Body B should be rotated one turn to the left. If you look at the picture for step #1 you can see how the back is straight and then curves way out to the right.
      Does that help?

      Posted on September 9, 2013 at 12:18 am
    2. I tried doing what you said, but even if you rotate Body B, there are no 2 sides of the same length. Something is off.

    3. Did you line up the center backs?

  8. any chance you have larger sizes to share? 😀 i just went to make one for my son but didn't notice the size until i had printed it off. he's in 12 or 18 mos clothes and i only have one shirt to try it with so i don't want to mess it up by trying to make it bigger and making something really wonky!
