The cat-loving 'Shake It Off' singer was snapped outside the studios for The Late Show with David Letterman.
Taylor oozed sex appeal in a slinky sequin detail frock with a plunging neckline - and it seemed just the frock for this Halloween!
While the star definitely doesn't need any help in the figure department (check out those pins!), the contrasting side panels on her dress are a clever way to give the illusion of a slimmer shape.
Want the same helping hand? It works way better when the panels are a darker tone - this Little Mistress Printed Panel Bodycon Dress, £58, is perfect.
We're all for Taylor's Halloween-esque colour scheme too... way chicer than a pumpkin costume, eh?!
