Make a Baby Romper from a T Shirt

If you're tired of the ho-hum pastels and puppies for your baby's clothes, you can easily make your own rockin' duds for your little stud from vintage tees or band shirts. Here are instructions on how to make a romper (also known as a onesie.)

Steps

  1. Get a youth-sized t-shirt and a pre-made romper (aka a "onesie").
  2. Turn your t-shirt inside out. Fold both the t-shirt and the romper in half and lay the romper on top of the shirt, lining them up at the fold. Trace.

    See how the crotch on the romper puffs up because it's in a shorts shape? Ignore that. You'll have to fudge a bit for the bottom part. Use the image as a guide.

    You should narrow the sleeves (or take them off altogether, up to you). So basically you're cutting a chunk out of the armpit and then letting it widen for the legs.

  4. Unfold and cut just outside of the line you just sewed. Go ahead and cut your bottom line too, just make sure you leave enough to hem or you'll get an underwear shape.
  5. Fold it over and trace what you've just cut onto the other side. Don't let your cat help, he doesn't have thumbs.
  6. Sew the armpit line on that side and cut.
  7. Attach your closure. If you use snaps, reinforce your fabric with something that doesn't stretch so they hold up better. Make sure your closures are so that the flaps point toward each other when you go to close it. So both sides should be facing up when laid flat.
  8. Stop here if you don't mind a homemade appearance. Otherwise, you'll want to hem. Cut that little diagonal slit between the crotch flap and the rest of the leg so your corners don't bunch.
  9. Turn the finished romper right side out .
  10. Dress your child.

Tips

  • Using a youth t-shirt will minimize bulk in the shoulder area. If you want to use a larger shirt, you will need to make the neck smaller. A seam in the back will do this for you.
  • If you don't use sleeves, you can hem the armholes for a more finished look.
  • For a larger shirt, it's better to avoid using sleeves unless you're willing to do a major overhaul.

Things You'll Need

  • Youth t-shirt
  • Sewing machine or needle and thread
  • Pen
  • Scissors
  • Closure (snaps, snap tape, hook&loop tape)
