No, we're not too sure what a 'trouser dress' is either, but doesn't it look amazing? Kylie continued to take New York by storm on Tuesday, leaving her hotel in her stunning printed yellow tunic and wide-fit cream trousers.
A white clutch bag and gold peep-toes added extra oomph to the outfit, not that it was needed, and Kylie's huge grin shows she feels fantastic, too.
The singer has been spending time promoting her new book, Kylie Fashion, and ramped things up a notch when she arrived at the Saks Fifth Avenue launch in a see-through black minidress.
She's definitely on a roll.
