We'll try to keep it simple...all of our high quality corsets are steel boned corsets with three layers, the fashion fabric layer or outer shell, twill interlining (the strength lining), and twill lining on the inside. There is a waist tape running through the corset that helps support the corset so that it doesn't tear at the seams. This is so important since the tension is highest at the waist. Metal rings (grommets) are at the back. All genuine corsets have laces and the grommets are there to protect the laces from ripping through the fabric. The laces are threaded through the grommets and help tighten your corset aiding in the tension of your garment. Instructions for lacing and/or unlacing the corset are included. These durable, high quality corsets have a front bust with steel loops and knobs that fit perfectly together to help you get in and out of your corset with little effort. There are steel bones (see vertical boning throughout garment) to help keep the corset wrinkle free and to prevent it from collapsing under tension. Spirals or spiral bones on the side are properly tipped with metal end caps to prevent sharp ends from creating a hole in the fabric or poking your skin. Ouch!!! The ends are rounded and coated to prevent sharp ends from ripping through the fabric and help waterproof the bones preventing rusting. At the top and bottom of the corset is binding that helps keep the bones in place. At the bottom on the inside of some of the garments, the binding also secures garter tabs. These tabs are inconspicuous should you choose not to use them to attach garter suspenders to keep hosiery up. Fashion corsets, on the other hand, while attractive may have plastic boning, zipper closures, and thinner layers or layer of stretchy fabric. They are not be be confused with authentic, high quality steel boned corsets and do not have a lifetime guarantee. Real corsets tend to be a bit more expensive. How to Decide Between a Waist Cincher vs a Corset Waist cinchers will on average deduct about 1 – 3” from your waistline while wearing them. They can be worn during workouts and are more comfortable to sleep in than corsets. Waist cinchers are easier to conceal underneath clothing and can be worn (depending on the person) for more hours during the day. Waist cinchers are shorter and good for flattening the tummy, but won't provide the waist training you desire for hourglass curves that an under bust or over bust corset will. They are an excellent choice for short torso body types. Under bust and over bust corsets offer more drastic or dramatic results and instantly deduct 2 – 6” off your waistline when wearing. With proper waist training, the results you have with the corset on will be just as noticeable with the corset off.
