Hitting snooze! Rumer Willis looks leggy in summery shirt dress as her sister Tallulah chooses nightie and slippers for friend's house party

Rumer Willis is known for her incredible sense of style.

And that was most certainly the case as the 27-year-old daughter of Demi Moore and Bruce Willis attended a dinner party in West Hollywood on Saturday. 

The actress looked sensational as she flaunted her lean legs in a striped shirt-dress, as she was joined by her sister Tallulah Willis, who opted for a nightie and slippers.

Trendy sister: Rumer Willis, 27, attended a dinner party in West Hollywood on Saturday

Feeling sleepy? Joining Rumer was her 22-year-old sister Tallulah who clad her gym-honed figure in a skimpy cotton lavender nightie- which she teamed with a pair of white slippers

Putting on quite the flamboyant display, the red-haired 22-year-old clad her gym-honed figure in a skimpy cotton lavender nightie- which she teamed with a pair of white slippers.

She also rocked a pair of stripey socks and edged up the attire with a choker and gold chain.

The sleepy attire let her plethora of tattoos to be on display while she mingled with pals and engaged in a phone conversation, while Rumer strutted her much more thought-out attire. 

Different looks: Rumer (L) strutted along in a pair of metallic gold stiletto's and looked like she'd put more effort in to her attire while Tallulah (R) added an element of edginess with a choker 

Her metallic gold stiletto heels were in stark contrast to Tallulah's soft-touch kicks.

The Sorority Row star's one piece was cinched in at the waist with a thin black belt, while a few buttons were undone at the top- giving it an effortless vibe.

Sprucing up her rising starlet status, she clad her perfectly chiselled face with a pair of jet black shades which matched her slick long tresses which cascaded past her shoulders.  

The beauty looked care-free as she clung on to a drink and some notes in one hand, while carrying a small black structured handbag in the other. 

While Rumer and Tallulah both have a flair for unique fashion along with their sister Scout, 24,- it is Tallulah who has been the more alternative of the lot.

She has also been an avid supporter of the 'Free The Nipple' campaign and she regularly pose topless pictures on social media, with aptly placed coverings. 

While Rumer likes to join her in supporting the campaign, she is also hard at work proving her own status in Hollywood.

Sociable: Her red-hair was up in a half bun and she was spotted having a quick chat with a pal over the phone 

Rumer will next take her cabaret act to Feinstein's at the Nikko in San Francisco from June 22-23.

'My musical taste comes completely from my dad,' the nepotistically-privileged socialite told Billboard's Soul Sisters podccast this month. 

Her next acting gig is playing Emily in this year's indie film adaptation of the Manhattan period musical flick, Hello Again.

It's based on Michael John LaChiusa's 1994 off-Broadway chamber musical, which was based on Arthur Schnitzler's 1897 play La Ronde. 

'The deed is done!' Tallulah is the most alternative out of the three sisters and is an avid supporter of the Free The Nipple campaign
