Reviews

Gotta Snug Fast

"Got an XL Sonic onesie and was pretty chuffed at it fitting as well as it does, snug in all the right places and so so warm! It's perfect for lounging in the coming colder months but it's also perfect for having a giggle or dressing up for your friends with! Really nice quality too, no scratchy sensations. Fits a 6ft bigger build of 100kg just right, though go for 2xl if you want a looser fit. I have slippers that go with the fit but have yet to go out in public in fear of Eggman attacking! Gotta go fast!"

Suburb Snorlax!

"Oppo, you done it again, I been holding out on hard times but this year I wanted to keep it simple and recalled you guys sold Onsies. I am beyond pleased with the quality and care that goes into the products on your site! It’s soft, feels luxurious and like I’m in a cloud. And it has not one, not two but four pockets! I want to design a Munchlax poncho to go with, but a Munchlax onesie for kids would be a must have…"
