for a moment i thought u are going to start a new fashion
statement of hanging trousers' waistband round your neck.. lol
depending on your body size n shape, if u are a beanstalk then u
could do that to get the measurement, but for a person who is
curvy, its not going to get a accurate fitting.
its ok for guys to wear women's pants.. especially those super
skinny leg, looks good on guys as well.
but i would reccomend u to try it before buying because with the
current trend of pants, sometimes its abit hard to figure out how
it would look as a whole, not only the waist measurement
matters.
