All-denim ensembles are infamously one of the hardest looks to pull off.

But Selena Gomez made it work – and look effortless – as she was spotted on Sunday.

The singer was sporting a denim playsuit with a distinct retro feel, revealing her lean limbs as she stopped at a gas station in Tarzana, California.

The 21-year-old looked cool with the sleeves and shorts of the one-piece rolled up, and she accessorised it with a thin black belt.

And adding another colour into the mix, the Come & Get It songstress wore a pair of neutral sandals.

Though she concealed her eyes with oversized sunglasses, Selena’s long brown mane most definitely gave her away.

Selena was recently involved in a court dispute with perfume manufacturer Adrenaline, Inc., but the case was dismissed by a Los Angeles judge.

Yet, it could still end up costing the singer millions of dollars.

Selena counter-sued the Florida based company in May after they accused her of backing out of a mufti-million dollar endorsement deal for a new perfume, to be sold in her name.

Adrenalina claim they invested more than $2 million into the manufacture and marketing of the fragrance after she agreed to be spokesperson for the brand in 2011.

Part of that marketing strategy included running a competition that gave fans the opportunity to have a say in the development of Selena’s perfume.

The company – which is now out of business – claim Selena failed to honour a promotional appearance at Macy’s in Miami, as well as further promotional obligations across Mexico.

They also claim the singer and actress’ management company, July Moon, sent them a letter stating the Disney star would terminate her contract within 30-days.

That decision, they say, had a domino effect that led to manufacturer Victory International handing them a $1.2 million lawsuit for the production of the star’s fragrance.

Selena counter-sued the company in April, claiming she backed out of the deal after the company owed her $5.2 million in lost earnings because the business deal fell apart.
