I’ve designed this giant lobster onesie to be a mix of practicality, comfort – and fun!
 
The claws are removable pillows: You can knit the claws on their own to have some giant, crustacean-themed throw pillows!
The tail fin has an opening: The tail fin is attached to the front, leaving the back open for you to put your feet down and walk.
The tail fin also has a pocket for your feet: You can even slip your feet inside one panel of the tail fin to keep them cosy!
