Caroline has legs that measure a whopping 51.5 inches from hip to heel
Caroline Arthur, who lives in Melbourne, Australia, has legs that measure a whopping 51.5 inches from hip to heel.
The 39-year-old said: "I believe that they are definitely the longest in Australia and, as far as I know, in America too.
"The lady in the Guinness Book of World Records (Russia's Svetlana Pankratova) has legs that are 51.9 inches long so it's quite close.
"Because it's so close I think it is worth contacting them and finding out exactly where they measure from and getting an official, accurate measurement done."
Dermotherapist Mrs Arthur is 6ft 2in tall – meaning her legs account for around 69 per cent of her frame.
She has always struggled to find clothes that fit her long slim physique and is the subject of stares and astonished glances whenever she is out in public.
She said: "Mostly, I enjoy it. My friends always have to be a bit prepared when they venture out with me because people do stare – especially if I'm dressed up in heels.
"I just know by now that if I'm going out with people in the evening, I'm going to get a lot of attention so I am sort of used to it.
'I believe that they are definitely the longest in Australia and, as far as I know, in America too'
"I have had a few people say nasty things but mostly it's great and people are really nice."
But body positive Mrs Arthur has not always been so confident in her appearance – she recalls being a self-conscious teenager who wanted to dress in ways that would disguise her height.
She explained: "I definitely didn't embrace my height and there was a real period where I didn't feel beautiful or attractive at all.

"I just wanted to be the same as everyone else. "I started modeling when I was around 15 and that gave me confidence.
"My legs featured in a lot of stocking commercials and things but I was also rejected from a lot of jobs because of my height.
'People do stare – especially if I'm dressed up in heels'
"I was told that I'm too tall for Australian beauty standards and couldn't model clothes because they just wouldn't fit me.
"So as much as I did get work because of my long legs, I also got knocked back for the same reason."
At the height of her modeling career, Mrs Arthur won herself a famous fan in Beatle George Harrison.
She said: "I was modeling at the Melbourne Grand Prix and he was there. Apparently, he was really amazed by the length of my legs and asked to meet me.
"I didn't even realise who he was but I talked to him and we even danced together. Someone eventually told me who he was and I couldn't believe it.
"I remember going home and telling my mum and dad and they were like, 'How many people get that opportunity? And it's all because of your long legs!'"

Mrs Arthur does seem to have passed her impressive height on to her two children, 13-year-old Cooper, who is already 6ft 2in and 'midget' of the family, Zoe, who at 15 stands at 5ft 9in.
Her mother, Janet Ware, however, is only 5ft 2in.
Mrs Arthur, who is married to builder, Cameron, says her mother-in-law makes her clothes for her and that her husband thoughtfully designed their house to have 10 ft ceilings and extra-high kitchen worktops to accommodate his super-sized family.
Her husband said: "Caroline and I are about the same height but when we stand next to each other, her hip is much higher than mine."
"Being married to her is definitely good for my posture because I have to stand up straight.
"I think her legs most definitely are the longest in Australia – I can't imagine any longer.
"She was working in a shop when we first met and I'd go in and see her. I never really had a thing for tall women; I just had a thing for Caroline."
Their children say they are both excited by the prospect of seeing their mother in the Guinness World Records.
