Doctors say Skinny jeans can seriously damage muscles and nerves.
A 35-year-old woman had to be cut out of a pair after her calves ballooned in size.
The Journal of Neurology, Neurosurgery and Psychiatry reported she'd spent hours squatting to empty cupboards for a house move in Australia.
By evening, her feet were numb and she found it hard to walk.
Eventually, while in a park, she collapsed, and had to crawl to a nearby taxi to get to the hospital.
Doctors believe the woman developed a condition called compartment syndrome, made worse by her skinny jeans.
Consultant neurologist Thomas Kimber described her as a "fashion victim."
