Quick Black Widow DIY Baby CosPlay


Our nephew wanted to be Captain America for his 8th birthday. Naturally, that turned into an Avengers  themed party. We decided to dress all the kids as Avengers characters and since we only have one girl in the family, you know who became Black Widow.

Originally, I planned to sew her a little jumpsuit, add the S.H.E.I.L.D. arm patches, throw on a belt, and color her hair red using temporary hair spray (I also heard about hair chalk but I wasn’t sure how to use it). Unfortunately, the week took over (I got busy) and fear gripped me (about chemicals on her hair). I woke up Saturday morning and realized that I had a few hours to turn my 9 month old into the badass Avenger team member, Black Widow. I was able to use items that I already had lying around the house so it cost me nothing to join in the cosplay fun.


  • Long-sleeved baby bodysuit
  • Pair of black skinny leg jeans
  • Metallic silver pen
  • Black Sharpie
  • Long piece of Velcro
  • Elmer’s glue
  • Elmerps spray adhesive
  • One quarter sheet of white scrapbook paper
  • One tenth sheet of red scrapbook paper
  • One tenth sheet of black scrapbook paper

The baby already had a black, long-sleeved body suit (onsie) so I grabbed that and paired it with a pair of black Joe jeans that we picked up at a clothes swap. Black jumpsuit? Check!

I’m not an artist so I went to the internets to help me with the S.H.E.I.L.D. patches and belt. I found this great diy tutorial that gave me the specifics on what to make. Then I did an image search for the patches to print the patches so I could Sharpie them on to my scrapbook paper.

These looked great so I saved the image, printed it on regular paper, and then used them to trace the image into scrapbook paper. After coloring it in with a black Sharpie marker, I cut the circles out and attached them to her onsie using Elmer’s glue. I wanted the patched to stay on for photos but not stay on forever.

For the belt, I printed out a photo and used that to draw a silver hourglass on a sheet on white scrapbook paper with a sliver metallic pen leftover from our wedding eight years ago! I drew the hourglass and then cut out a smaller red hourglass from leftover scrapbook paper, and then an even smaller hourglass from leftover black scrapbook paper. Once I felt like the proportions were right, she IS a baby after all, I glued the red onto the metallic hourglass and the black onto the red hourglass. Making the belt buckle was the easy part. Deciding what to make the belt out of was a bit trickier.

I originally wanted to use elastic but all I had was white polyester elastic and I didn’t think it would look good if I dyed it. I also didn’t want to buy a black elastic. Luckily, I had some leftover black Velcro (my sewing stash always has Velcro! Lol) that worked perfectly. Black-Widow-CosPlay-Belt

I fitted the Velcro around her waist and made a cut. Then I cut about an inch off the rough side of the Velcro and an inch off of the  opposite end of the soft side of the Velcro. I used spray adhesive to attach the belt buckle to the end of one side of the Velcro and let it dry for about an hour.

I didn’t end up coloring her hair, though that would have made the outfit perfect! In the end, I was able to use items I already had lying around the house and it only took about 30 minutes.

Next time, I would totally do the hair though.
