My recollection was from an interview of her that I watched years ago. But, I found an article that discusses a book written by the woman whose name was Dolly Kyle. Here's an excerpt:

Kyle said she first met Hillary Clinton when Bill brought his future wife to Hot Springs for his unsuccessful congressional race, and asked Kyle - who he was also dating at the time - to pick them up at the airport.

'I picked Billy up at the airport and he had this dowdy-looking middle-aged woman with him.

Kyle was 'shocked' by Hillary's unkempt appearance, poor hygiene and matronly clothes, and didn't believe it was the same girl Bill had moved in with as she looked so bad and she smelled so bad she just didn't believe this was Hillary.

'Seriously, I thought this was some kind of a joke Billy was playing on me.'

Hillary's eyes glared at her from behind 'coke-bottle-thick lenses' with an air of real hostility. Her thick eyebrows melded together stretching across her forehead.

'I couldn't imagine why Billy would haul such a person in the plane with him in public. She was wearing a misshapen, brown, dress-like thing that must have been intended to hide her lumpy body. The garment was long, but stopped too soon to hide her fat ankles and her thick calves covered with black hair,' Kyle said. But was Hillary's smell that Kyle says she remembers most.

'In that moment I noticed that the woman emitted an overpowering odor of perspiration and greasy hair. I hoped that I wouldn't gag when she got in my car,' she said. 'The sandal-shod woman with lank, smelly hair stood off to the side and glared at everyone.'
