According to The Guardian:
That's right. If we learned anything during the whole of 2014, it's that ankles 'were the new sideboob'. This ends a years-long search by a host of media outlets, such as the Guardian, Daily Mail and Evening Standard, who have all been seeking the 'new sideboob' (even if they can't agree whether it is one word or two).
Back in March 2013 the Daily Mail thought they had finally found the new sideboob:
But clearly it wasn't to be. Just a few weeks later the London Evening Standard seemed convinced 'side butt' was the new sideboob:
However, 'braless' clearly fell short of such a lofty billing and the trail for 'the new sideboob' went cold for nearly a year. It wasn't until July 2014 when the Daily Mail thought it may have ended this journalistic quest for the Holy Grail:
'Pelvage' is apparently a portmanteau which blends 'pelvis' and 'cleavage'. But what it definitely isn't is 'the new sideboob' because, as the Guardian has finally confirmed, ankles are the new sideboob.
We now wait to hear what the new ankles are.
