I had such amazing feedback on my free Newborn Romper Pattern that I went ahead and created another blog post with a sitter romper pattern.  The steps are identical to the newborn romper, but the size is different.  I absolutely love creating custom, unique outfits for my clients.  I found that although I have so many amazing vendors I purchase outfits from, there is something very empowering about being able to create my own unique looks for a client.  I also found that I would be searching and searching for the EXACT color or style I wanted for a baby, and would spend a ton of time searching and never really find exactly what I envisioned.  Sewing outfits for my milestone sessions has given me a lot of creative control over my sessions.

There are two ways to create this pattern.  The first is shown on the top picture with Conner.  It includes full legs and is my favorite for boys.  On Amelia, the second image, I simply removed the legs and made a cute version where the legs show.

I have shared my simple pattern with many of the photography students I mentor, as well as a few photographer friends who sew.  This romper has two curved seams and two three straight seams, so it really is something anyone with basic sewing skills can make.

Directions for Sewing Your Newborn Romper

Please note that this romper is for use as a PHOTOGRAPHY PROP only and babies should never be left unattended in this outfit,

as it does tie around the back of their neck thus isn’t meant to be worn as an everyday outfit.


1 yard of stretch knit fabric OR a second-hand sweater with stretch (my “go-to”)

Thread to match

1 yard of yarn to use for the tie

Step 1

Print off all three images on 8×5 x 11 inch standard printer paper.  Tape pieces together, and cut out around the pattern.

Step 2

Pin your pattern onto your material (two pieces of fabric), then cut out a front and back for your romper.  I make it easy on myself and use a roller cutter with a mat board (approx $20 at JoAnn’s).  I lay the material flat and cut out two identical sections.   If you have fabric that frays, you will want to cut the pattern 1/4 inch longer on the legs for a bottom seam.  I typically use upcycled sweaters and use the finished bottom for the legs, so I don’t have to do a finishing seam on the leg bottoms.


Step 3

Cut the bib off of the back of the romper (see pattern) with a curved cut.


Step 4

Pin and sew a zig-zag or stretch-stitch  seam in the top of the bib, approximately 1/4 inch.


Step 5

Pin the front and back together, right side to right side (as in, the outside of the fabric, what you want show, facing in).  Sew a stretch or zig-zag stitch along each outside edge of the leg with 1/4 inch seams up to the spot in which the back of the romper ends.  Make sure to trim the excess fabric off so that when you sew the drawstring seam it isn’t blocked by the excess fabric.


Step 6

Turn the romper right-side-out, then lay romper flat with the front-side facing down.  Starting at the right side at the top of the bib, pin the fabric down the side of the bib and all the way around the back of the romper.  Sew a stretch or zig-zag stitch at a 1/2 inch.  This will be a curved seam that the drawstring for the neck will be threaded through.



Step 7

Again turn the romper inside out, pinning around the crotch and legs, finishing up your sewing with a 1/4 inch seam with a zig-zag or stretch stitch.



Step 8

Turn your romper right-side out, and using a small safety pin, thread your drawstring though the edge of the bib, around the back, and up through the other end of the bib.



Now go find a cute baby to photograph in your romper!!
