Petti Romper

May 6, 2011

A few weeks ago, I got a message from a friend of mine. It read: Have you ever made a petti romper? “A petti what?!” I thought, and immediately went to Google. I found pages and pages of precious, lacy little outfits donned by girls dressed in their Mommy’s pearls and I immediately knew I needed to figure out how to make one! I was smitten!


I found some tutorials for them, made from satin and stretch lace, but I wanted to go a different route. I scoured and my friend chose a color she wanted. I waited with baited breath for the package to arrive, then anxiously finished my orders ahead of it, dying to get my hands on the fabric!


This romper went together so quickly! Sofie wasn’t as thrilled about it as I was (and was bribed with candy in order to cooperate!) but she willingly tried it on repeatedly. The only downside about using the ruffle fabric is that the romper isn’t going to shrink as small as some of the others. I know they fit infants through toddlers, but this romper is more size specific.

I cut my fabric 24″ long, because I wanted to be able to take ruffles off if necessary, and 19″ wide. At the top of the fabric, I cut right under the ruffle above where I wanted to start.

I put the fabric with right sides together, and measured 4″ from the bottom (so 4 ruffles since it’s 1″ ruffle fabric) and marked it with a pin. Then starting at the top, I carefully lined the ruffled up and pinned each one. Then I stitched at 1/4″ seam allowance, stopping at the bottom pin, leaving the last 4″ unsewn.

Then I serged the seam. If you don’t have a serger, zigzag the edges to help prevent fraying.

Center the back seam,

and cut the piece underneath to match the piece left unsewn.

Matching the ruffles again, pin one leg,

then the other.

As with the back seam, sew at 1/4″ seam allowance, then finish the edges.

Now, to help the romper stay in place, I needed to add elastic along the top, which is why I left the extra fabric at the top above the uppermost ruffle. Fold the fabric down, making the ruffle the very top of the romper, and starting at the back seam, sew a casing with the widest stitch on your machine (to allow for stretching), stopping an inch or so from the start of the seam.

Thread 3/8″ elastic through the casing, according to the size needed for your romper. For this 2T/3T size, I used 18″.

I overlapped about 1″ and stitched the elastic together, pulled it back into the casing, and closed the hole.

And that’s it!


After trying this on Sofie, I realized the legs were too long. So I cut 2 ruffles off and reinforced the bottom of the seam with a simple zigzag on the regular machine over my serged seam.

Then find a willing model and have a blast!
