10 Minute Onesie Dress – Easiest Dress Ever

Hello, when you read this DIY you will be like “That’s it, I’m buying a sewing machine.” SO SIMPLE. It’s a onesie with a skirt around it, cute AND comfy:

Find out how to make this 10 Minute Onesie Dress (with finished seams through no work of your own!) after the jump…

10 Minute Onesie Dress

1.  Acquire one onesie and 1/4 yard of cute cotton fabric (mine from City Craft, isn’t it pretty?  get it online here: Amy Butler Sweet Jasmine in Navy).  Pre-wash and iron:

2. Fold one long edge under 1/4″ and iron, then another 1/4″ and iron and stitch in place to create your  hem.  jacinda also suggested you could use a cute tea towel and it would already have a hem, so you could skip this part and have like a seven-minute onesie dress.

3.  Sew a basting stitch along the other long side:

3.  Pull the bobbin thread to gather it until it is twice the width of your onesie (when it’s slightly stretched out).  For my size large gerber onesies i made mine 18″:

4.  Fold it in half right sides facing:

Sew together and finish the edges by serging, sewing with a zig zag or overlock stitch or cutting with pinking shears:

Turn your skirt inside out to admire:

5.  Now take your onesie and draw a line at the waist across the front and back with a washable or air-erasable marker:

Turn it inside out and do the same thing on the inside:

Now turn your skirt inside out and arrange the seam to one side:

With your onesie right-side out, slip it headfirst through the skirt with the front facing up, like so:

Unbutton the bottom of the onesie and flip it over the skirt.  Line up the edge of the skirt with the lines you drew and pin through all the layers so you’ve trapped your skirt edge in onesie fabric:

Sew all the way around with a 5/8″ seam.  So mine is a little messy, who cares?

Flip it all around!  DONE!  And your unfinished skirt edge is encased in onesie softness so as not to bother baby:

See, onesie goodness:

Yay!  What do you think?  Do you want a sewing machine now?  I swear you can do this, so easy.  You could also applique or embroider something cute to the chest for matchy fun.

Love this ! Thank you for posting, you just made my daughters Minnie Mouse costume so easy for me to make ! 🙂


[…] you’re wondering how I made these onesie dresses, it was pretty simple. Here is a link to the blog I stole the idea from Like this:LikeBe the first to like this post. Tagged […]


So happy to find your cute blog! I’m also now following you on FB! I just adore this cute little onesie dress. I will be making these for my cute little granddaughter!

I look forward to many new ideas! thanks!!


did mine as a separate skirt with elastic then made shorts to match as well – material had blue and purple hearts so visofixed a heart on onsie and painted a border around. so two onsies – one with blue heart one with purple heart and a skirt and a pair shorts all in a couple of hours!Thanks !


Great tutorial! This definitely took my more like two hours to do, but I’m now inspired to try more after my first successful sewing project Thanks!


I like this. If your child is too old for onsie; try t-shirts. It works as well.


I am about to have a go at making one for my little lady 🙂 I am so excited. Thankyou for sharing the tutorial xxx

Think I could make this work for a blousy bottomed boy outfit? I have a few baby t shirts that are a little long on my 7 month old. Plus, I don’t like using plain tees because they ride up constantly. Could I make the skirt, sew it to the bottom of the tees and close up the bottom to make leg holes? Is that crazy?
Thanks for any input!


I made this last night after my little one went to bed and when I tried to get it on her this morning I found that attaching the skirt made the onesie too small to go over her head, it seemed to kill the stretch. I might try it again with the next size up onesie, but am wondering if I did something wrong?? Someone commented to use a zig zag stitch instead, but am I missing anything else? It was pretty disappointing to make something that looks so cute that doesn’t fit anymore!


I thought about that too and decided to add elastic to the fabric. Before you attach skirt position the elastic on the wrong side of the fabric, just under the finished edge, and sew it on, pulling tight to stretch it as you go.


If you make a waist casing for the skirt using the onesie, then arent you effectively shortening the onesie at the waist by a good couple of inches? I think that would make the onesie too tight at the crotch.


TOOO CUTE! I have a 2 week old, and I realized the other day that she has no dresses in her wardrobe (that’s probably because mommy doesn’t either). sSe does have a TON of onsies of all sizes though. I cant wait to make up a handful of these for her to have a cute comfy outfit she can wear out and about and also roll around in at home. Thanks for the super easy idea!


Super cute! My SIL is due in April with a baby girl and I CANNOT wait to make her one of these!!! Thanks for sharing!


Love this!!! My babies aren’t in onsies anymore, but I used this concept to make my 6 yr old a dress with a shirt and Christmas material. Thank you!!!!


The really great thing is: You don’t have to throw (or give) away your old (and often so cute) onesies – I just made a nice dress for my girl (she’s turning 3 soon) by cutting the part with the buttons off (it didn’t fit any longer in the length, but she’s quite slim – so the “shirt”-part still fits) and sewing a skirt following your example at the lower part. I’m so glad, I found this idea at your page. Thank you so much for it – I’m happy having found a way using the onesies I grew fond of 😉 !


I was wondering if some one could explain a bit differently than Teresa did last august about adding elastic so you still have the stretch at the waist. It is not clear to me the way she explained it. Thanks in advance


I love this! But quick question: Do you do anything to allow a little “give” in the onesie? Her head, shoulders, and arms still need to fit through to get the dress on. Have you ever had a problem with that? What could be done for that?

I love this dress!! I just made my third one. This time my daughter is older so I made it with just a $5 old navy white t-shirt. Turned out super cute!! Thank you so much for sharing!!


Thank you for this! We are having a grandaughter born in july, and this will add to the things I can sew up for her. I really like that you don’t cut the bottom off, I hate waste….love it!
