It’s so fun to dress little boys up even if it’s not that practical. Sometimes I indulge myself. I would love to see this in a black suit and black satin bias binding. It would look like a tux! Or if you make your own bias binding, use the same fabric to make matching pants!
Baby Suit Jacket Sewing Pattern and Tutorial
- Old suit jacket
- sewing tools
- 3 yards bias binding either 1/2″ or 1/4″ (I found 1/2″ to be a lot easier.)
- 12 mos little boy suit jacket pattern – Get the pattern at the end of the post!
2. Save a front button to use.
5. Fold the collar in half. Put the pattern on the fold. Line up the the fold line with the fold line of the collar. The fold lines only need to match up at each end. You will have a fabric collar and a felt collar.
You might have enough fabric leftover to make matching suit pants! Maybe even use the side pockets as details!
6. With right sides together sew the shoulder seams together on the fabric and the lining. Iron seams open.
7. Next you’re going to sew the collars on. The felt collar (under collar) will go on the fabric and the fabric collar (upper collar) will go on the lining fabric. Match center backs with neck edge toward the jacket. The edge of the collar will line up with the square edge. Sew right sides together. Iron seams open.
8. With right sides together sew all four sleeves into the shoulders. Match the notches withe the shoulder seam.
9. With right sides together sew side seams together from body to sleeve. If you cut the sleeve hems off, you will just end at the sleeve hem. If you didn’t cut the sleeve hems off, you will sew from body to sleeve to lining sleeve to lining body. The lining with be folded when you sew it. Iron seam allowances towards the bakc.
10. Optional: Sew the collar seam allowances together. This is a very professional technique, especially if you do it by hand. It will keep the two jackets together nicely.
Put the lining inside the fabric jacket. Sew the felt collar seam allowance to the fabric collar seam allowance and push all the other seam allowances and fabric pieces away.
11. Pin all edges together. Basted edges together at 1/8″.
11. Trim any wandering edges so all edges line up nicely.
12. Finish edges with bias binding. Where the collar joins the body you will have three curves. When I folded my binding around and was sewing it down, I sewed with the face of the jacket up from fold line down around the hem to the other fold line. Then I sewed the binding down with the face of the collar up from fold line up the collar to the other fold line.
13. If you cut the sleeve hems, finish them with bias binding.
14. Add button and buttonhole right under the lapel fold.
Try it on your little man and take him somewhere nice!
