Item 1
To determine your chest size, wrap a measuring tape around the fullest part of the chest (usually around nipple height). The measuring tape should be snug around the body -- but not squeezing too tightly -- and level across the back. If you don't own a measuring tape, they are available at most discount department stores or on Amazon.
Pant Waist
Pant waist refers to the waist size that fits you best for most brands of pants. The waist size is the first number on a pant clothing label (a 32x34 pant size would be a 32" waist size). If you are unsure of your pant waist size you can estimate it by measuring yout waist around the belly button and adding 2 inches.
Fit Preference
The fit preference determines how tightly the t-shirt fits and is a matter of personal preference. Note that a t-shirt will always fit more tightly after it comes out of the washer and dryer and become more relaxed over the course of a day of wear.
Item 6
Fabric weight is measured in ounces per square yard. A lighter fabric will reveal the shape of your body more than a heavier fabric. Lighter fabrics are great for working out while heavier fabrics are warmer and can be more durable.
