The Seagull Your Kid Was Born to Play
The Kid's Seagull Costume Onesie is a fleece onesie for children featuring sublimated graphics, an attached hood with a stuffed beak, hand covers with wrist openings, and sewn-in fleece wings along the sides and sleeves. If your kid has ever sprinted across a parking lot screaming at nothing in particular, congratulations — you have found their costume.
Seagulls live by one rule: everything is theirs now. Your child already operates on this same principle. The onesie just makes it official.
Design & Details
The in-house design team made some very deliberate choices here — the sublimated graphics and poly-filled beak do a lot of the heavy lifting in selling the full seagull experience. The center-front zipper makes getting in and out easy, which parents of young children will recognize as an actual gift.
The hand covers keep the look going while the wrist openings let your kid's hands stay free for critical tasks like candy collecting. The fleece wings are sewn directly into the sides and sleeves, so spreading them dramatically at a family gathering requires zero effort and maximum commitment.
Mine. Mine. Mine. Mine.
The Kid's Seagull Costume Onesie is built for school parades, fall festivals, and any occasion where your child plans to be loud, fast, and deeply unbothered. Pair it with an attitude of total ownership over every french fry in a five-foot radius and the look is complete.

We believe that costumes have the power to create some of life's best moments. That's why we started Made by Us. This diverse selection of costumes and accessories are all artfully designed and expertly crafted by our talented team of artists, designers, and developers.

Each project begins with a passion for true quality–embroidered patches, faux fur cut with care, and hand-selected fabrics that are as durable as they are comfortable. Those are just a few examples of how much craft and creativity we put into each and every product. Just for you.

No matter how much time it takes, our goal has always remained the same–to create products that inspire your life's best moments–the big, the small, the funny, the spooky, and the sweet. The moments we all cherish. That's Made by Us.
