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!"

Tolles Kostüm

"Hatte den Overall als Kostüm für meinen Mann gekauft. Super Stoff und bequem. Nummer größer bestellt, damit noch Thermo-Sachen darunter getragen werden können."

Schöner Überzeugung.

"Schöner Überzeugung."

Thomas W. (5/5)

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."

More than I hoped for

"The suits I ordered look great and are super comfortable. They are as advertised and that is a huge deal for me, since hardly anything is these days."

Jacquelynne G. (5/5)

Looks great, good quality

"Hard to go to bathroom while wearing if you have a vulva."

The Ultimate Halloween Costume

"My wife and I bought matching Shadow and Sonic kigus for Halloween (Shadow for her, Sonic for me) and couldn't believe how good their quality is! Regarding the Shadow kigu specifically, everything from the face, quills (all-important nub tail included), chest floof, inhibitor ring sleeves, and air shoe ankle cuffs. . . It's all perfect! The material itself is very cozy, too. Highly, highly recommended. Can't wait to see which characters come next!"
