Crop it like it's hot in Sofia's Alexander Wang top

Sofia Richie seemed to be having the time of her life when she joined fellow party girls Paris Hilton, Christina Milian and Karrueche Tran at a private party for Galore magazine.

The teen model showed off her flat abs in a T by Alexander Wang crop top that she teamed with a quirky pair of red and white striped pants.

Equal parts sporty and sexy, the bra top had a ribbed texture with a racerback design. Wear it with a comfy pair of fitted sweatpants and sneakers or dress it up with leather leggings and ankle boots.

Paris does have quite the history with Sofia's older sister Nicole as they famously starred together in reality series The Simple Life from 2003-2007.

In the pages of the publication, Sofia said she was known as just being a member of the Lionel family - which started to change once she finally tapped into her own interests.

'I went through it for a really long time, just feeling really in their shadow, but I grew out of it,' she told the publication. 

'I tried to separate myself as much as possible, figure out what I liked to do and how to get it done my own way instead of having them consistently helping me out. It’s a work in progress, but I’m trying.'
