DIY Necktie Onesie

Depending on when my baby boy arrives, he’ll have one, maybe two, weddings to attend this summer so of course he needs some stylish attire to wear. Since he’ll be tiny and it will be hot out for both events, I’ve been smitten by the little applique-style neck tie onesies that I’ve seen at stores and on Etsy (see below). However, since my mom is an adept sewer and I’m trying to improve my own skills, with her help I decided to make my own.

I won’t lie…as we started on the project, I was totally intimidated. But now having made a few with her help, I feel I could do it on my own. Since the pieces are so small, you could effectively use either a sewing machine or just hand-stitching to do this. I’ve included a download for our pattern in the supplies list to make it easy. Throw him in some baby trousers and my little guy will look quite dapper!

What You’ll Need
plain onesie
1/4 yd patterned fabric
all purpose thread to match
tie pattern
lightweight iron-on interfacing
iron-on hem tape (or fusable webbing)*
an iron
sewing pins
sewing machine*

1. Apply light weight iron-on interfacing to back side of patterened fabric. Flip over (pattern side up) and iron for about 30 seconds until the interfacing adheres.
2. Pin tie pattern to patterned fabric. If using stripes, check the stripe angle for your preference as you pin.

3. Cut out tie pieces at the solid line. This allows for a small seam allowance to the dotted sewing lines.
4. Pin the patterned sides of the tie knot to the tie body together at the dotted stitch line and sew knot to body using your sewing machine or a small, tight running stitch.
5. Flip right side up and use iron to press the seam flat. Press under the seam allowances using your iron. Review for shape and symmetry, repressing as needed.

6. Place tie on onesie and match up the neckline with the top of the tie. Cut off a small piece of iron-on hem tape and place under the top edge of the tie knot, tucking under to ensure no tape is sticking out. Once it’s in the position you desire, iron until secure. Repeat process with a large tape strip, placing it down the center of the back of the tie body and several smaller pieces along the tie bottom and edges as needed.
TIP: You can skip the iron-on hem tape and simply sew the tie onto the onesie but the hem tape secures the tie in place and makes it much easier and faster to sew on.
7. Use a sewing machine or a small, tight running stitch to stitch down the edges of the tie. Be sure that your seam allowance is also getting secured by your stitches and not poking out.

  1. This is just about the cutest thing I’ve ever seen! Love it!

  2. I love it! Where did you find the colored onesies? I always have a tough time finding a plain, colored onesie. I experimented with dying my own but would need to invest in something above and beyond Rit dyes before I would be confident that they wouldn’t bleed and/or fade.

      @Nicole – they’re from Buy Buy Baby. PS, do you know what you’re having for #2?

      • We don’t.. and I have none of that “mother’s inclination” that they talk about. 🙂 I waver between boy and girl, I was feeling “all girl” for awhile but realized it was because we had decided on a girl’s name but were still waffling on our boy name. Now that we have them both decided it’s back to 50/50 feelings. We did find out with Amelia so this is new territory for us!

    Love it! So cute…

    TIP: You might want to think about pre-washing (and shrinking) both the onesies and the cotton fabric before you sew them together…Since you’re dealing with 2 different kinds of fabric (knit & woven) they might shrink differently if you wash them after you’ve finished!

    It adds and extra step to the prep work – wash, iron, then cut out pattern but it may help keep it looking the way you want it.

    Hi! I love the tutorial and I have a quick question (as a newbie to sewing). When I was sewing the tie onto the onesie, I noticed that the onesie fabric “pulled” quite a bit and there was some puckering. I haven’t sewed with knits before, so I am assuming that it has something to do with my technique. Any suggestions for how to sew this correctly and prevent my problems?
