Ill fitting bras are a common source of mid back pain, or pain and stiffness in the neck and shoulders, often accompanied by headaches.
Six in 10 women suffering back pain, stiffness in the neck and even headaches because of a lack of support, the British Osteopathic Association warned.
Tight belts are also commonly responsible for numbness and a burning sensation along the outer thigh, leading to hypersensitivity to heat in the shower or bath.
Natasha Hatwell, from Bravissimo, said women needed to check their bra size regularly.
"The most common mistakes are wearing a cup size which is too small with a back size that's too big," the Daily Mail quoted her as saying.
"This means the weight is taken by the shoulders, that leads to back pain."
She added that part of the problem was that most women assumed they were one size and kept buying the same bra, "but boobs change for all sorts of reasons".
Other items of clothing found to take a toll on the body included thongs and G-strings, which caused a fifth of women friction burns, and flip-flops, which can lead to an ugly-sounding condition called claw toe.
