    Splash Adult Snapsuit

    I really love the print of this snapsuit a lot. It's fricken adorable. I have had to have a seamstress alter the garment to fit better around my waist though. That may be a personal preference issue though. It's a quality garment, the snaps are sturdy, and the print really makes me feel super dooper adorable!

    This is my first snap suit and it feels great to put on over training pants or a nappy. Perfect fit and I absolutely love the print. The snaps are secure and easy to do up. Quality in general is great. Thanks again Rearz

    I wasn't originally sure it would fit my wide hips, but it worked perfectly. The onesie fits snugly and is very cozy, the snaps on the bottom are comfortable and hold up extremely well. I love the print! More kawaii please!!!
