A thigh gap is the space between a woman's inner thighs, visible when she stands up. It is considered a desirable trait indicative of being thin and physically fit. If a woman's thighs do not touch each other, she is considered to have a thigh gap
Social media has exacerbated the popularity of the thigh gap, with Twitter accounts devoted solely to bodies that have achieved this beauty objective. However, a thigh gap can also be indicative of being underweight. There is also a bone structure component to thigh gaps, so they cannot be achieved for some individuals without severe deprivation.
