We've had many of our customers ask what the difference is with Flat Steel, and Spiral Steel boning in corsets....
Everyone has their own personal preference when it comes to the type of corset they lace themselves into. No which one is better than the other, but there are their differences- that provide different wearing experiences. Depending on where you will be wearing your corset and the look that you are going for, all comes down to the type of corset boning.
Let’s start with flat steel boned corsets, most people have the assumption that because they are stiffer and add more of an extreme look that they are better- though this is not always the case. Flat steel boning is made of strips of spring steel sheets, carefully blunted on its sharp edges and coated with a rust protectant. It is much more difficult for fittings, and for the wearer to wear. Due to the rigidness of the boning, when tension is applied to one end of the corset the other end will automatically fluctuate in the other direction- causing unwanted gapping in places. This problem is dominantly seen in people who have a much smaller waist to bust and hip ratio. Flat steel bones are a lot wider and more durable- this may appear to be a better option. Obvious assumptions are that flat steel bones are thicker and stiffer, offering more support and shape. A flat steel bone will skim the outermost convex points of those curves.
Spiral boning I find- doesn’t get as much credit as it should. This boning normally provides a better fit, as it hugs the hips and bust much more. The flexibility of the boning allows you to apply a bit more tension to the corset, and is not as constricting as a flat boned corset. From experience, curvier girls fill out spiral boning corsets better- as many say “what doesn’t bend, breaks.” This isn’t to say flat steel boning will break but they don’t bend as comfortably as spiral boning. Spiral boning easily trace the swell of a bust, then the curve of the ribcage, a subtle indent of the waist reduction, and then gracefully round the hip bone- most corset makers use spiral steel. Performers and entertainers usually wear spiral boning corsets- as they need much more flexibility upon performing.
The type of corset ultimately comes down to personal preference, which is no help if you are shopping for your first corset. Kinky Miss Lingerie is more than happy to help when selecting a corset- and remember to always do you research before purchasing!
