Dannii joined her sister in New York yesterday (19 June) where they were snapped working their own takes on summer city-cool.
Kylie, 45, paired boyfriend jeans with a floral top and red pointed courts as she arrived at a downtown hotel.
Showing how to go from day to night NYC-style, she later swapped it for a striped monochrome dress, keeping to her signature tousled waves.
41-year-old, Dannii, nailed daytime-glam with black leather trousers and a floaty top with a statement neckline.
They're contrasting looks, for sure, but we just can't decide whose outfit we like best!
