These clearance Snapsuits only have a snap crotch. We will be restocking the Snapsuits with snaps down the front once these are gone. At the moment XS still has the snaps down the front.


Bring the Lil’ Monsters crew along with you! Featuring Draco the Dragon, Puffy the Pink puffball, Unicrest the Three Eyed Dino, Midnight (Blue) & Twinkle (Purple).


This super cute and comfortable Snapsuit is made with cotton/spandex spandex giving it a great stretchy feel while keeping it as soft as cotton. 


Our Snapsuits give a tight, discreet fit while helping smooth lines and holding diapers/pads in place without the fear of shifting or sagging. Features a metal snap crotch with 4 snaps.


Fits similar to a standard female T-shirt sizing (size up one size if you are used to male sizing). This Snapsuit can stretch up to a few inches longer than listed below and can shrink up to 15% after washing.

    It's so soft! I'm 6'5", and the large is just a tad bit tight, but I love it like that!

    I like the fit and feel of this onesie. The pattern is one of my favorite ones. They hold well and do what they are designed to do.

    Fits great.

    I bought this and it fits really well. I enjoy the snaps going down the center. I also recommend buying the onesie 1 size up. It wont be loose and it will fit just right.

    Great Onesie but runs small

    Posted by Mark on 2018 Apr 30th

    Love the feel and fit, but does run a bit on the small side - purchases a 2XL and the fit with my diaper is a bit too snug (and pulling apart the gaps between the snaps) - might consider sizing up when ordering
