I bought my three-year old, Ada, a Chuggington costume when we went to Kid to Kid for Halloween costume shopping. Ada is all about any type of vehicle and loves watching Chuggington so I’m hoping she’s still excited for it when Halloween comes.

I wasn’t able to find a costume for my one year old, Zoey, and I like the idea of them matching…. at least for one more year before Zoey has more of an opinion. I decided to take one of my current onesies for her and attempted to make it into a matching Chuggington costume. I decided to model Koko; one of the female Chuggers. After going through Zoey’s clothing, and realizing how few plain onesies we have, I decided to use one of our tie-dyed onesies. The top of Koko is lime green and her bottom half is purple so I decided to use the onesie with a correlating top color and a pink bottom that I was hoping wouldn’t clash with Koko’s paint scheme.

I then took some convenient paper from an Amazon delivery and folded it up to put inside the onesie so the fabric markers wouldn’t go through to the back of the fabric.

I set Ada up with her crayons, markers, and pencil crayons and found a good image of Koko online.

I started by drawing out the main elements of Koko: outlining her mouth, her ‘nose’, the separation between the lime green and purple, the black outline on the front bottom, the grey eyes and eyebrows, and finally the eyes. After I finished the main details I went on to do the main color changes: the dark color in the nose, the area above her mouth, and the grey and dark purple at the bottom. Afterwards all I had to do was fill in the main areas.

I wasn’t sure how on point the onesie was, even though I had Ada’s approval, so I decided to draw the whole Chugger on the butt of the onesie. I had a printable of Koko from a previous project and pulled out our lightbox so I would be able to trace it better. I put the lightbox inside the onesie, turned it on, placed the printable on top of the light, laid the butt of the onesie overtop, and made sure it was lined up where I wanted it.

Unfortunately, it was hard to see Koko through the fabric of the onesie so I used my black fabric marker to draw any features I was 100% sure about. I then went on to use pointillism on any features I wasn’t sure about. I decided to do this so it would be easier to cover up any mistakes… learned my lesson from a previous time.

After I drew as many of Koko’s features as I could through the fabric I removed the lightbox and compared my drawing to the printable.

Using the printable as a reference I drew out the rest of Koko. I also added minimalist train tracks to the picture and labelled it with ‘Koko’ and ‘Chuggington’.

After I completed the outline, and waited fifteen minutes for the ink to dry, I went in and colored Koko.

All that was left was to iron the onesie to set the colors and cross your fingers that the kids will enjoy their Halloween costumes. I was able to do this during Zoey’s nap so if you have onesie that would work on hand and fabric markers this would be a perfect last minute costume.

I’d love to see your onesie alterations! Love how you can use anything you want to add. Feel free to connect with me through the comments below, on my Facebook page, or through Instagram.
