My hat was the central part of the costume, and I borrowed the dress from a friend (I did not make it).
To make the hat, I secured the brim of a large floppy beach hat with cardboard to provide a strong base, and then on top of the brim, I used fiber-fill stuffing to give the hat its dome shape. I glued battery-operated fairy lights in a swirling pattern on top of the white cloth that secured the stuffing, and then layered two colors of iridescent organza over the lights and added three layers of ruffled organza ribbon. Lastly, I attached alternating strands of blue and whitish-pink iridescent ribbon to make the tentacles, and finished it with white fabric on the underside to clean up the mess underneath.
