She's known for her love of making a style statement, and Nicole Richie did just that while still staying comfortable on Sunday.
The 33-year-old was seen stopping for frozen yoghurt in Los Angeles, wearing what appeared to be a vintage nightgown.
The silk sleepwear was a teal colour with green trim and blue detailing, and hung off Nicole's thin frame, also revealing a hint of her white bra underneath.
She also wore a pair of black slip-on shoes and had a matching leather backpack slung over her shoulder.
Nicole sported a pair of large round sunglasses over her minimally made-up face, and slicked her pink hair down.
The reality star turned fashion designer admitted to Into The Gloss earlier this week that she rarely washes her brightly coloured pixie cut.
