Summer Baby Romper

Unsie is the most hassle-free & comfortable baby romper ever made. Unsie based their style off the vintage one-piece swimsuits from the 1920s. Find more styles at our website. 

This piece comes with a tank top, shorts and a pull-down panel in the back.

The neckline is also made so that you can pull the suit down over your baby's body if they lock their knees or you want to avoid pulling a dirty suit over their heads.

95% cotton, 5% spandex. You select your fabric & size and we sew it out. 

Care Instructions

Turn Inside Out. Wash Cold, Dry Low.


We make these suits to order so if you do not like the black binding we finish all our jumpsuits with just add a note that you would prefer your binding be made from the same fabric as the jumpsuit.


We use fabrics purchased from Art Gallery Fabrics. We also use a couple of deadstock fabrics. Because the Unsie requires 5% spandex for stretch we cannot offer 100% organic cotton Unsies.

Art Gallery Fabrics were selected because all their cotton used in their knits is from the USA (although weave and print is done in S. Korea), their mill is ISO 9001 certified, they only work with Mills that are buying raw material from Fair Trade Cotton Producers and all their products are OEKO-Tex certified. Also, their knits are the softest we've touched and their prints just beautiful. 

About Unsies

Designed by a parent who hates negotiating buttons and snaps. 

If you are tired of dealing with snaps or saggy pants that won't stay put, try Unsies.

Unsies is made without any fasteners or elastic so it is extremely comfy on baby's tender skin. 

In 2007 Rosalee Rester designed Unsies because her son had sensory issues and did not tolerate lumps, cold metal, elastic, zippers or velcro against his skin. She also got really tired of seeing him run around with his snaps unbuttoned. Unsies fits like a body glove and is made from 100% fabric. It comes with a pull-down panel (dropseat) in the back for easy diaper checks.
