Teenage Mutant Ninja Turtles Adult Leonardo Costume Onesie | Nickelodeon Costumes
Lead the team with this Adult Teenage Mutant Ninja Turtles Leonardo Costume Onesie. Officially licensed by Nickelodeon, it blends ninja discipline with cozy, lounge-ready comfort. Crafted from soft, low-pile minky fabric, it zips up the front for quick on-and-off and features rib-knit cuffs to keep the sleeves and ankles in place during training, meditation, or relaxed couch sessions. The attached hood completes the look with Leonardo's blue bandana, printed eyes, and floppy side ties for full shell-squad identity.
Printed details showcase Leo's blue wrist, elbow, and knee wraps, along with his turtle abs and brown belt bearing a bold L. This versatile onesie is perfect for parties, cosplay, movie nights, or lazy days—officially licensed and built for comfort without compromising style. Suit up, zip in, and lead with confidence (and epic naps) in this TMNT Leonardo costume.
