New York's newest panoramic observation deck has brought in new dresscode to stop visitors seeing more than they expected.
The Summit One Vanderbilt attraction's glass floors and reflective ceilings were dreamt up to produce a view of the Manhattan Skyline as never seen before.
However, since last Monday, the Summit's guests are now warned against wearing certain items of clothing to prevent "unwanted exposure".
The new exhibition, called "Air", is housed inside three floors of the 427 metre tower.
With skyline views and reflective surfaces there was already a warning to guests to bring shoes that will not damage the polished flooring and ruin the illusions.
