We can't guarantee you the luck of the Irish with the leprechaun Piggyback costumed, but we can guarantee you'll get laughs and attention everywhere you go wearing it. Thanks to a clever optical illusion, this costume looks like you've got a little leprechaun pal carrying you around wherever you go (maybe it was one of your wishes he granted you). Our Piggyback outfits go down a treat wherever they are worn.To get the adults leprechaun Piggyback costume ready for action, just stuff the legs with rolled up pieces of newspaper.
