Authentic Steel Boned Corsets are sized by your natural waist size minus 4 to 6 inches depending on how much compression you want. Plus sizes (natural waist of 38" or more) should order 6-8 inches down, as the more fluff you have the better able the corset is to redistribute and fill out the corset Novice corset wearers will likely not achieve the same level of cinching as experienced corset wearers.
Orchard Corset has an exclusive system for rating the curviness of a corset that we call Silhouette Levels. This system also accounts for your underbust and hip measurements and helps place you into a corset that is best suited for your body type and desired results.
To determine your natural waist size you measure your natural waistline or about an inch or so above the belly button (where your natural bend occurs-often the smallest part of your tummy). Pull the measuring tape taut, but not tight. The same is true for measuring your underbust (and fullest part of your bust when shopping for an overbust corset) and your upper hip measurement. Again, our Sizing Tip Blog is a great source of information.
