Samantha Cameron's 'disappearing' dress gives illusion she is fading into Number 10

Twitter users have been split by Samantha Cameron's dress choice today as she re-entered Number 10 with her husband.

Her sartorial choice had the unusual quirk of blending in with her frontdoor, leaving her missing a middle.

The belt and dark colour around the waist of the dress leaves the Prime Minister's wife 'disappearing' into the famous black door behind her.

However others questioned the arrangement of colours on the dress, wondering if she was making a comment about the General Election without uttering a word.

Some compared the dress to the new constituency map for the UK after the General Election, or wondered if there was a hidden message in the arrangement of colours.
