A Cornell-educated artist and sculptor has come up with a highly bizarre, but probably very effective, 'personal space' creating dress.
Kathleen McDermott, who is currently based in Hong Kong, designed the motorized dress after experiencing repeated instances of men crowding her on public transportation networks.
The ruffled pink and white creation doesn't spring out suddenly in the fashion of an umbrella, as it looks like it might, but rather senses a looming presence, and slowly expands outwards.
'So I began to look for ways women could take more ownership over their personal space in public.'
Ms McDermott built the dress herself and used 'proximity sensors' to identify when a lurker gets too close for comfort, and plastic scaffolding within the garment to enable the hemline to expand.
Most of us have experienced unwanted leering on the subway, but plenty have dealt with worse in busy, thriving cities around the world.
A survey two weeks ago conducted by the Los Angeles Metro system, which covers trains and buses, revealed that one in five riders say they've been sexually harassed in the past month.
In Tokyo, the problem has become so alarming that their Metro system has introduced 'women-only' cars on their trains during rush hour.
