Assisting Tentacle

This costume would be worn like a backpack, with an arm sticking out by the side of the wearer. When the wearer places and object near the tip of the tentacle, it will actuate and wrap around it to hold it in place.

Expanding flower

The flower dress starts small and deflated, and then the petals/leaves will inflate while the bottom of the dress also blooms outward.

Movement bubbles

There are many small pouches all over the wearer’s body, and they inflate in areas of movement.
