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!"

Great quality, just as depicted

"Looks and feels great, only minor complaints are that it’s very warm (unsurprisingly) and that it’s very awkward to use the restroom in."
