Determining Fit & Proportion in Standard Sized Corsets (3 methods)

This article contains the same information as my video, “3 ways to Predict Fit & Proportion in OTR Corsets”. You may watch the video here if you prefer not to read – or you can continue reading below the video.

Before reading this article, you may want to catch up with some of my other corset fitting articles like “Shape of the Corset Gap” and “Troubleshooting More Fitting Issues“. Those videos and articles had focused on how a corset will look and feel on your body, and how to determine whether it’s a proper fit. However, there are ways to predict how a corset will fit your body even before you purchase it online! Making the most of size charts and fitting information can mean the difference between “fits almost like a custom” and “not what you expected”. It’s of absolute importance to remember that corsets don’t stretch the way most modern clothes do, and your bodies bones largely don’t compress.

The biggest issue I have with OTR corsets these days is that many companies still recommend that you choose your corset size based only on a 1-point measuring system (i.e. “subtract 4 inches from your natural waist”). But this is oversimplified. Different corsets will fit differently on different bodies, even if they’re the same size!

There is no reason why a corset company would NOT provide at least 3-4 measuring points (underbust circumference, waist circumference, high hip/iliac circumference, and then the vertical length of the torso) so you can determine the proportions and the length that will fit your body best even before you buy a corset. These proportions can be determined immediately by looking at the original draft of the corset pattern, or you can do some quick and simple measuring of the final corset to determine these proportions.

When I sell standard-sized corsets (either new OTR corsets or my own pre-made samples) I almost always ask the customer for their natural underbust/waist/iliac measurements and their torso length. I personally check their measurements against the measurements of the corset, and verify that the size they would like is going to fit them well. Doing this has greatly decreased the number of exchanges/ returns requested.

Some businesses already use the 3-4 point measuring system, and they may provide this information in 3 different ways:

1: Using size charts/ tablesScreen Shot 2014-01-07 at 3.52.24 PM

To the right, you see an example of a size chart for a corset. You want the waist of the corset to be between 3-6 inches smaller than your natural waist (depending on your squish level), but you want the rib and hip measurements to be as close as possible to your own natural measurements. This will ensure that the corset cinches the waist and NOT the upper ribs or hips (which are far less compressible), and thereby result in a more flattering silhouette and comfortable fit. Size charts are my favourite way of logging proportions of a corset, because I can check its measurements against my own natural measurements at a glance. Corset businesses that utilize size charts include (but are not limited to): Meschantes, Electra Designs, and Mystic City corsets.

2: Recommending that the customer’s measurements fall within a certain range

Screen Shot 2014-01-07 at 4.02.58 PMSome corset makers prefer not to use a size chart, but will instead recommend that your natural measurements be within a certain set of measurements. If you are on the upper end of this range, then you can expect the corset to have a larger gap in the back compared to if you were at the smaller end. Although this situation is better than a 1-point system, you may still end up with slightly uneven gaps in the back depending on where your own measurements fall and how large the given range of measurements is. Corset businesses that utilize this system include (but aren’t limited to) Isabella Corsetry, Starkers Corsets ready-to-wear samples, and Morgana Femme Couture.

3: Discussing the proportion (rib spring and hip spring) of the corset, rather than absolute numbers

Sizing information provided by Orchard Corset on one of their Level 3 listings

Orchard Corset is an example of a company that simplifies the measurements into a simple set of proportions – for instance, for a Level 3 silhouette corset you may find that the underbust (upper ribcage) circumference is 5-6 inches larger than the closed waist measurement, and the low hip circumference is 10-12 inches larger than the closed waist measurement. (Typically OTR corsets are made quickly so the measurements aren’t likely to be as precise as a custom corset, that’s why you have a general range.) Doing some simple math, this means that for a size 30” corset, the underbust will measure (30 + 5 = 35 inches), and the low hips will measure (30 + 10 = 40 inches).

In the next video/ article of the series (part 2), I will show you how to use size charts properly, to predict whether a corset will fit you or not *before* you purchase it. And in part 3, I will show you how to fairly accurately measure your own corsets. This will help you verify that the corset you just received in the mail has the correct measurements (they match the size chart/ ranges mentioned on the website) and that the corset will be likely to fit comfortably once closed.

Setting waist training goals – focusing on proportion

Back in 2010, I made a two-part video mini-series on waist training 101 – the basics that you should know before you start any corset training regimen. The very first thing I mentioned in those videos were setting goals for yourself – what waist size would you like to have, and why? Sometimes a beginner will tell me, “I want to have a 24 inch waist.” Well, do you want that to be your corseted measurement, or your natural measurement? One takes much more work than the other. (I had mentioned in a previous video that if you want a natural 24″ waist, you may have to lace down to 20″ or even less in the corset to be able to maintain that natural waist measurement.)

I also know women who have started out close to a 34″ waist, and want to be able to close an 18″ corset. While that’s certainly aiming for the stars and I don’t want to shoot down your dreams, it will likely take you several years and several corsets to properly train down to that point. Also, have you considered what an 18″ waist would like like on your frame? An 18″ waist may look out of place if you are 5’10” and 180 lbs. But for a petite woman who is 4’11” tall and weighs perhaps 100 lbs, an 18″ waist may not look out of place at all on this  woman. Instead of focusing on arbitrary numbers for your waist training goals, perhaps you should consider proportion instead as a way to determine your ultimate corseted goal. Below you’ll see a few examples (or you can just watch the video above to learn the same ratios):

Method A: The waist circumference = 0.7 x (hip circumference)

Where to measure your waist and full hip to determine your ratio.

This equation has been touted by doctors and athletes for years as being the modern accepted “healthy” and “attractive” waist-to-hip proportion. Women with a natural waist below 0.7x(hip circumference) often have a lower risk of cardiovascular disease, as it’s often a marker of carrying less visceral fat (the fat that physically chokes the organs in the peritoneal cavity, and is also metabolically more active than subcutaneous fat, releasing hormones that can lead to metabolic abnormalities). If a woman with a 40″ hip circumference were to calculate her goal waist based on this equation, then her goal waist circumference would be 0.7 *(40 inches) = 28 inches.

Method B: The waist circumference = your thigh circumference

Whether this goal is reasonable/ attainable often depends on your body shape. I have seen many pear-shaped women with shapely thighs (likely between 25-30 inches in circumference) because they gain their weight in their hips, thighs and bottom, often leaving the waist naturally small. In this situation, this method may be quite attainable. However if you are naturally an apple shape and you have a tendency to gain around your middle, while having thin legs and thighs (close to 16-20″ in circumference), this may not be the best goal for you.

Method C: The width of your hips = 1.618 x (your waist width)

This is likely the oldest equation. It’s based on phi, (aka the Golden Mean, formed from the Fibonacci sequence) and it is the ratio/ proportion that animals and humans alike are able to innately detect. This proportion is seen everywhere from the crest of waves and the form of a spiral galaxy, to the seeds in a sunflower and the honeycombs of bees. The closer that a person’s proportions adhere to the Golden Mean, the more attractive they appear and the healthier they seem to be overall. When it comes to setting your goals in this manner, you will need a stiff measuring tape, ruler or pair of calipers, and a mirror or someone to take your picture because this proportion is based on the planar measurement (the width of your hips while facing head-on) rather than the circumference. A woman whose hips are 14 inches wide will calculate their waist width as such:

Waist width = (14 inches)/ 1.618 = 8.7 inches.

With corsets, many of them pull the sides of the waist in primarily, bringing the waist in from an “oblong” shape more towards a proper circle. If you imagine that the waist is a perfect circle, then the width of the waist is also the diameter. From this, you can calculate your goal waist circumference if you wish = (8.7 inches)x 3.14 = 27 inches.

 In this situation, the waist measurement for methods A and C are actually pretty similar, but on you it may not be – method C would depend on how much of your hip circumference is distributed from side-to-side (i.e. hips or “saddlebags”), vs distributed front to back (in a full low-hanging tummy or a protruding bottom).

If you don’t like to crunch numbers, then you can simply invest in a “Fibonacci Gauge” or Golden Mean calipers, which are made with 3 “prongs” – no matter how wide or narrow you hold the calipers, the width of the larger gap in the prongs will always = (width of the smaller gap in the prongs x 1.618) so you will always be able to measure and mark out the Golden Mean. On any given day, no matter what your weight, you can use these calipers to mark out the width of your hips, and then compare that to the width of your waist using strictly proportion, but without having to focus on numbers. I personally love numbers, which is why I find the study of phi so fascinating, but I understand it’s not everyone’s thing. This Ebay store has the least expensive calipers I have found – I’ve already purchased 3 and given two to my friends. Do support a phi carpenter if you can.

So you can see, there are many ways that you can set waist training goals for yourself, using your own body’s shape and frame as a reference rather than using arbitrary numbers (which may or may not be realistic for you). It’s using what you already have to an advantage so you can know on a mathematical (and also a natural, almost subconscious) level, whether your waist is truly in proper balance and proportion with the rest of your body. You can also watch my video on waist-hip proportions and using the calipers in the video below.
