Bust Measurement: Measure around the fullest part of your bust.
Hip Measurement: With feet slightly separated, measure around the fullest part of your hips.
Pant Inseam: Measure from the top of your inner thigh to the bottom of your ankle. You can also measure the inseam of a similar style pant for comparison (measure from the inside crotch down the seam to the ankle).
Shrinkage: The sweatshirt material is mostly cotton and will shrink when washed. The pants will shrink approximately 1 inch in length if you line dry and about 2 inches in length if you put them in the dryer. The width will shrink a little as well, but will give a little when worn (just like your favorite jeans).
