Ruffle Romper Pattern

Adorable ruffled bottom romper tutorial with free romper pattern by Melly Sews
Sometimes I get to sew for girls, mostly for my adorable niece, who is modeling this outfit. She’s a little peanut, so this romper is 6-9 month size and today I’m going to show you how I made it and share a free romper pattern.
To start, I used the Ruffled Bloomers pattern for the bottom. Visit that post for instructions to download the bloomers pattern.  To download the pattern, subscribe to the Melly Sews Weekly Newsletter. AFTER you sign up, you’ll get a confirmation email – and you have to confirm or my email service can’t send you the free pattern. But once you do confirm, you’ll get access to not just this but several other free patterns. Woot!
(Please note: my patterns are licensed for personal use only. By downloading you are agreeing to this license. You may not use this pattern to make items to sell or redistribute it by any means without a limited production license. Contact me for further details. Thanks!)
(PS – if you have trouble finding either your confirmation email or the email with the pattern link, try checking your spam, trash, junk, bulk, social and/or promotional email tabs or folders. Free pattern links are also included in every weekly newsletter; these go out on Friday afternoons. Due to the number of subscribers I can’t email pattern links to individuals.)
I used 1/2 yd of fabric for this whole outfit, plus some 3/8 inch elastic.
This outfit is for size 6-9 months, and the original ruffled bloomers were only size 3-6 months. However, all I did to size up was add 1/8″ to the side seams of the bloomers. Easy peasy. If you need to make the pattern bigger or smaller, check out this post.
Cut out the pieces according to the bloomer tutorial and the instructions on the romper pattern. Use all extra fabric to create ruffles for the bloomers. I did 4 rows instead of 3 like the original bloomers, and finished them with a rolled hem instead of making tubes to ruffle. That way I maximized my fabric usage.
Sew the ruffles onto the bloomer back, and sew up the side seams of the bloomers, then set them aside.
For the romper top, sew the two back pieces right sides together around almost all 4 edges, leaving a hole to turn right side out. Clip the corners.
Turn right side out and press, pressing the raw edges in, and topstitch all around, closing the raw edges (my raw edges aren’t pressed yet in the picture below).
Sew the straps into tubes right sides together, matching the long edges. Turn them right side out and press so that the seam is on the center back. On one end of each tube, turn the raw edges to the inside 1/4″, press and stitch closed.
Sandwich the raw edge of each strap between the top edges of the two front pieces, with right sides of the fronts together. Stitch as you did for the back piece, clip corners, turn right side out and press.
Pick the bloomers back up. Mark a line 7/8″ down from the top raw edge all the way around the bloomers. In the picture below, my line is just above the top ruffle.
Turn the bloomers inside out. Press the top raw edge toward the inside 1/8″.
Turn bloomers right side out again. Sew a basting stitch right on top of the line you marked on the top edge. Use that basting stitch to gather the bloomers to the same width as the front of the romper.
Pin the bottom edge of the front of the romper just over the basting/gathering stitch line.
Pin the back of the romper the same way – EXCEPT that the back romper piece will overlap the front romper piece at the side seams. My back piece is on the right in the picture below, and you can see it overlapping the romper front.
Sew around the top of the bloomers, right on top of the basting/gathering stitching.
Turn the romper front/back pieces up and press.
Turn the romper inside out, and pin the folded edge of the bloomer down to form an elastic casing. Stitch casing in place, leaving an opening to put in elastic. Be careful as you stitch over the gathered fabric and go slowly so that you catch all of it in the stitching.
Thread elastic through the waist casing you just made. Sew the ends of the elastic together and sew the casing shut.
Add snaps to the sides of the romper, the straps, and the back. I used a total of 6 snaps (two on each side, one on each strap/back combo).
Finish the leg casings as in the Ruffled Bloomers tutorial.
And then revel in the cuteness!

    I just signed up, so I’ll comment! Beautiful! I’m thinking about ways I can adapt this (the bottom) to attach to a onesie for 11 week old Olivia!

    I was introduced to Melly Sews on Facebook. Thanks so much for the free patterns and tutorials! I have a question for you. What should I do to make this ruffled romper a size 3 months? Believe it or not, I want to make one for my big baby doll, Gracie. Santa brought her on my first Christmas, and she actually arrived in a polka dot romper similar to this, but since she is nearly fifty-five years old, that romper is loooooooog gone! :) Gracie has lots of cute clothes and keeps me company in my sewing room, but she might be missing her original outfit.

    Thanks SO much for keeping this going! My first grand daughter was born exactly 2 weeks ago & I am looking forward to all the future sewing projects for her! This romper is SO cute! (& I like anything with ruffles on the rear for baby girls!) Your site is great & I WILL be returning OFTEN! THX AGAIN!!
