Corset sizes are in inches, "size 36" means "36 inches". Please read measuring instructions carefully. Wrap a measuring tape snugly but not tightly around the fullest part of your bust. This is the size corset you should order. If you are between sizes (like 35"), order the smaller size. Corsets should fit snugly, you will be unhappy with a loose fitting corset. If you have a proportionately smaller waist, and want to use the corset to emphasize this, you can order the next smaller size. This will give you a snug fit around the waist with a little skin exposed on your upper back. For underbust corsets, wrap the measuring tape around your ribcage directly under your breasts. Order this size in inches (36 inches is size 36). What is the difference between a corset and a bustier? The standard definition is a bustier has cups and a corset does not, but manufacturers do apply their own terminology so this isn't a hard and fast rule.
