DIY Baby Boy Faux Vest Onesie

DIY Baby Boy Faux Vest Onesie TutorialI made this baby boy faux vest onesie for a baby shower gift.  I have to admit that I seriously considered not giving it and keeping it for a future baby boy that I may or may not ever have.   It was just too precious! I really like the color combination of the grey vest and the tan suede bow tie.  I ended up giving it as the gift after all but it was with much longing that I parted with it but not before I made a tutorial so that I could make another one if that time ever came!

Baby Faux Vest Onesie Tutorial

Baby Boy Faux Vest Onesie Tutorial

  1.  Make your own pattern by hand sketching a vest panel.  I used a onesie as my guide for the size of it.  To allow for seam allowance, I traced over the pattern again with two pencils hooked together with a rubber band.
  2. After I had made my pattern, I realized that I didn’t like the front part of it.  It was too high so I angled it down a bit.
  3. Cut out two pattern pieces.  I made one of the pattern pieces a little bit longer on the center side so that it cold overlap on top of the other piece.
  4. In true refashion form, I used a pair of grey pants for the vest fabric.
  5. Cut out both vest pattern pieces out of the fabric.
  6. Lay the fabric pattern pieces on the onesie to make sure they will fit.  They need to be larger than the onesie so that when you finish the edges, the vest will be the right size.
  7. Serge the edges of the vest pieces.
  8. Fold the serged edges to the back of the vest (wrong side of fabric) and iron.
  9. Pin the smaller fabric vest in place.  I tucked the top of the vest under the collar part of the onesie.
  10. Before you pin the larger fabric vest panel piece on, sew a straight line down the edge of the part that will overlap with the other vest panel.
  11. Following the edge and sewing underneath the onesie collar, sew the vest onto the onesie.  (Make sure you don’t sew the onesie shut!) Sew the smaller panel first and then the bigger panel second.   Hand sew on some buttons.

Baby Suede Bow Tie Onesie Tutorial

Once the vest is complete, it needs a little bow tie to pull it all together! I made this one out of tan suede fabric. The texture of the bow tie adds another cute detail to the outfit.

Suede Baby Bow Tie Tutorial

  1. Cut a rectangular piece of fabric.  My piece was about 3.5 x 3 inches.
  2. With right sides together, fold the fabric in half and sew both sides leaving an opening in the center.
  3. Turn the bow tie piece right side out through the hole that was left in the center.
  4. Hand stitch the hole using an invisible stitch. Mark the center of the bow tie rectangle. Pinch the center down and pin.
  5. Cut a second piece of suede for the center of the bow tie.  My piece was 1.25 x 4 inches but I ended up cutting off some of the length.
  6. With right sides together, fold the fabric in half and sew the unfinished edge.   Use a safety pin and turn the tube inside out.
  7. Wrap the tube around the middle of the pinched rectangle.  Make sure that the hand stitched hole is on the bottom and covered by the tube .  Using a needle and long piece of thread, sew the back of the fabric tube together.   Keep the thread attached to the bow tie.
  8. Hand sew the bow tie onto the center front collar of the fabric onesie.
