Who wore it best? Amal Clooney and Jessica Alba prove they have a flare for fashion in matching monochrome wide-legged trousers

When it comes to competing with Amal Clooney, there's not many people who stand a chance. 

But Jessica Alba gave George's accomplished wife a run for her money as they stepped out in similar styles on Thursday.

And it was a case of goodbye skinny jeans, hello flares as both women opted for a '70s vibe in matching monochrome wide-legged pants.

Human rights lawyer Amal, who married her Hollywood beau last year,  went for a full-on bell bottom with a heavy pattern, which made the most of her slim, long legs.

She teamed the jazzy pants with a simple black sleeveless top and a large shoulder bag as she made her way into an office building in  New York.

Meanwhile, on the other side of the US, actress Jessica was sporting a virtually identical ensemble.

She also added a simple black top, but smartened up the look with a blazer as she headed to a cafe in Venice, California.

The '70s wardrobe staple is back in a big way this spring/summer, after years of designers pushing skinny silhouettes.

And it's not only flares which are making a comback; disco glam, hippy prints and long suede skirts are all must-haves for 2015.

And Amal can really play with her style now she lives in the home of cool fashion - New York.

Get Amal's retro look with a pair of print pants

She may be from England, but her wardrobe is bursting with high end Italian designers. Gucci, Versace, Miu Miu, the list goes on. And for an outing in NYC, Amal Clooney wore flared print trousers by another brand from the boot shaped country, Giambattista Valli.

George Clooney's wife teamed the psychedelic print with a sleeveless top, Stella McCartney shoulder bag, and platform shoes for an all-out 70s retro vibe.

This isn't the first time we've seen the A-lister in pants by the luxury label. She wore a yellow and black chevron patterned version just last month. Are we sensing a theme here?
