Everybody knows that a romper is a fashion-statement piece! I was ready to make a statement but instead of going out and buying an expensive romper, I bought a cheap, oversized T-shirt and upcycled it into the romper I’ve always wanted! Check out my tutorial and learn the tricks of this fashion transformation.

Easy DIY romper

For this very cool upcycle, I used this oversized T-shirt. I couldn’t wait to transform it into a gorgeous romper. 

Trace shorts

Trace shorts 

First things first! I used a pair of spandex shorts as a template and traced around them adding an inch of seam allowance. I suggest making the shorts a little shorter so that there is enough fabric for the top part of the romper. Once I had traced the back piece I also traced the front. 

How to make a romper

Once I had finished tracing the shorts, I used a ruler to just straighten the tops and make sure they were even. 

Cut out the shorts

I then went ahead and cut the pieces for the shorts. 

How to sew a romper

Sew the shorts 

I placed the fabric pieces right sides together and then pinned the inner crotch area. I sewed along the pinned line. You can sew with a straight stitch or with a zig-zag stitch. 

Sew the side and crotch seams

With the front and back pieces sewed together, I placed them, right sides together and sewed the side and crotch seams. 

Seam rip the pocket

Remove the pocket 

I moved on to work on the top of the romper. First, I seam ripped off the pocket from the oversized tee. I then folded the T-shirt so that there were four layers of fabric. 

DIY dress to romper

Trace a T-shirt 

I used a T-shirt I owned as a template and traced around it adding an inch of seam allowance. While I was tracing, I tucked the sleeves under the T-shirt because I would trace them separately later. I pinned the folded T-shirt so that I would cut all four layers.

Sew the top

Sew the top

I placed the front and back pieces, right sides together, and sewed them at the shoulder seams. I laid the top flat and once I had my sleeve pieces cut out, I matched them along the armholes.

Sew on the sleeves

I pinned the sleeves to the top and sewed them on. 

Dress to romper

With the sleeves safely sewed on, I pinned the bottom of each sleeve and the rest of the side seams and sewed. 

Cut down the front

Add a front zipper 

To make the perfect romper, I wanted to add a zipper to the front. I folded the top in half and then cut down the center of the front of the top. 

Sew on the zipper

I then went ahead and pinned one side of the zipper in place. With it safely pinned, I sewed it on. I repeated this for the other side. 

Topstitch the zipper

I decided to topstitch to give the romper a nice, clean finish. 

Pin together

Sew the romper together 

The next step was putting the romper together. I pinned the waistline of the top and shorts together, all the way around, and then sewed. As I mentioned at the beginning of the tutorial, I suggest cutting the shorts shorter so that the top can be a little longer. I didn’t do this so I ended up adding fabric to the middle. To see this step go to 9:05 in the video tutorial.
