When creating halloween costumes, I always look first to the shape of the body – where do the natural lines flow, what geometry do their suggest?
From a legibility standpoint, the UFO is an absolute dream of a starting-off point. The imagery is so distinctive, so recognizable, that even a slight nod in its direction would communicate its meaning.
The peplum skirt as a tractor beam, the halter top as the ship’s antennae, the bust points as the ship’s lights – these were all a product of looking at the shapes of a UFO, and finding garment references that matched, rather than trying to force one shape onto another.
