The Basic Instinct actress opted for light and bright clothing on the summer July day as she donned a simple white dress that was adorned with colored geometric patterns, and a grey lining on the side of the outfit, which flaunted her famous legs.

She paired the dress with flawless white sneakers, a big black tote bag she carried over her right shoulder, black sunglasses, and a white sun hat that covered her blonde tresses.

Sharon added a nice pop of apple-red color to her lips, completing her outfit.

The mother-of-three appeared to have no care in the world as she roamed the streets of West Hollywood with her friend as they posed for pictures and relaxed after a day of rug shopping.

Her fellow laughing buddy wore a beige shirt tucked into khaki pants with a dark brown belt and light brown shoes. 

The duo were seen in the shop with a row of rugs surrounding them as they talked and laughed with the storekeepers. 

The Casino star appears to be on an ongoing shopping spree for her home as the actress also shared a picture on her Instagram posing with her interior designer friends in her renovated bathroom.

Sharon Stone recently opened up to AARP Magazine about her dating life and what fulfills her. She told the outlet, 'At this point, I get more satisfaction — physically, spiritually, emotionally — from a smile, a laugh, a warm conversation or a really sexy look.'

She added: 'You know the way a man can look at you? Where you know he really sees you? I don't want to be with someone unless it's like that.'

The actress/activist, who split with Michael Greenburg in 1990 and later Phil Bronstein in 2004, raises three adopted sons: Roan Joseph Bronstein, 16, Laird Vonne Stone, 11, and Quinn Kelly Stone.

Sharon will next be seen in The Masterpiece co-produced, directed by and starring James Franco. 

The film is based on the non-fiction book The Disaster Artist that tells the story of the 2003 cult film The Room and also stars Dave Franco, Seth Rogen, Josh Hutcherson, Hannibal Buress and Zac Efron.
