The funniest photo we’ve ever taken

“The fit was easy to adjust, and the second I picked him up everyone lost it. The costume stayed comfy for our quick photo session.”

Zero dignity. Ten out of ten.

“He looked deeply unimpressed, which somehow made it even better. Easy on, easy off, and absolutely worth it for the reactions.”

Instant Halloween icon

“The little arms sit perfectly in photos and the straps were simple to adjust. We were laughing before I even finished putting it on.”
