Taking measurements

Hi Guys, sorry if this is a bit of an “anaari” question but how do you take correct measurements for Shalwaar kamiz. I’m sure a number of us are going to order stuff from our home based designers so i thought i’d find out from you ladies what the correct way of measuring is.
Eg. how do u measure your shoulder?
what about your waist measurement, is this the same as the waist on your jeans eg 28 inch.
I hope some one can enlighten me! :slight_smile:
