Have you ever seen a woman in a miniskirt or a man in shorts and thought, "Wow, those are the perfect legs!" Well, a plastic surgeon who spent months studying pictures of attractive legs thinks he may be able to explain what makes the perfect pair, according to The Daily Mail.

The surgeon spent 12 years looking at more than 550 photos of models, athletes and celebrities, as well as famous Roman and Greek statues and even Barbie dolls. He found that the main aspect of the "perfect leg" was straight bones that gave a "line" appearance from the top of the thigh all the way down to the ankle. The most attractive legs have curves only at the knee and the calf, which, he says make the leg look both delicate and strong.

"As soon as the column departs from the straight axis, it deviates from our perception of beauty," he wrote, according to the news source. He adds that women in particular need some curves to their legs, however, to maintain their gams' "sexiness."

A concave curve above the ankle is most attractive, and the best legs, the expert says, do not have symmetrical curves on the inside and outside of the legs.

So why all the fuss about legs? According to the news source, the surgeon says that "over the last 50 years, with the changes in women's fashion, legs have become and important element of seduction. The first common denominator of all attractive legs is their straightness. Attractive legs are straight and in continuity with the thighs. The straightness of the leg models who advertise leg stockings and lingerie is noticeable."

Those who are feeling self-conscious about their legs may want to speak to a plastic surgeon about their options. According to the American Society for Aesthetic Plastic Surgery (ASAPS), liposuction can help remove unwanted fat from the thighs, while a lower body lift can also treat sagging skin and fat in the thighs, buttocks and hips.

Those who are concerned about the appearance of spider veins also have options, ASAPS reports. These dark, large and often bulging veins can be treated with sclerotherapy, which involves injecting an agent into the veins. This irritates the veins, causing them to scar and thus become less noticeable. Patients who are curious about the procedure should speak with a board-certified plastic surgeon about their options.
