Relying on old body measurements and pattern drafting instructions

There is a certain bit of nostalgia when looking back in time. We often say, "They don't build things like they used to," implying that we paid closer attention to quality and details. This same kind of thinking is also found in pattern making and sewing. There is a general assumption that the way things were done in the past are better then they are now. Some pull out old measurement charts and drafting instructions to recreate the past for a better present. We don't even have to go very far. There is the hope of a stylish outfit made of a 1950's sewing pattern and thinking that it will fit.

Before I go any further, let me say there is nothing wrong with looking backward and trying to understand how things were done. It is a fun exercise to draft a pattern using old instructions or sewing up that vintage pattern. This is about using old body measurement data and pattern drafting instructions to create modern clothing.

There are some key factors that make up a size - height, weight, girth, and shape. I suppose in the 1890s pattern makers and tailors were just beginning to understand the relationships between each of those factors. At least for men's clothing. Women's clothing was still a guessing game requiring customized fit. It wasn't until the 1940s that we began to see the connection to height, weight, and girth. Statistical analysis could finally show that when one factor changes, the others do as well. The studies done by Ruth O'Brien and her committee allowed us to see and understand body proportions and shapes and use that information to predict overall size. This information was not truly implemented until the 1950s and 1960s. Other studies have come along to add to our knowledge. A study in the early 1970s expanded our knowledge of children's body measurements. Another study, SizeUSA, was released in 2004 and greatly enhanced our knowledge of the US population using 3D body scanners.*

If you draft a pattern using older drafting instructions and body measurement charts, you will create something that is based on that time's understanding of body proportions and measurements. If that is your goal, then all is well and good. But if you find a free measurement chart dating back even 50 years, then you are placing your product in the 1950s.

We know this because not only has our understanding of anthropometry increased, but we know that the body measurements of a population change over time. If you are interested in creating your own line, it is in your best interest to obtain the most recent (and reliable) measurement data you can.



*Unfortunately the SizeUSA data is held behind a very expensive lock and key. Access is only available to those willing to pay a pretty hefty sum despite the study receiving tax dollars. Some ASTM body measurement charts have been updated to incorporate the study data. The ASTM children's body measurement chart is a mash-up of data that incorporates multiple studies dating back to Ruth O'Brien's 1941 study and some more modern data.

Vintage pattern reivew : Simplicity 5040

It's rare that I find a vintage pattern in my size, or close to my size, at the thrift store. I can't help looking through them anyway. I have yet to make up any of the styles that I've acquired over the years because I would need to grade them up or down in order for them to fit. I was happy when I found this one, Simplicity 5040, in my size and in a style that I like.

I initially assumed this style would have a side zipper and that the skirt was gathered. How else would one get it on? There is no back zipper and only the button front closure that ends at the waist. I was a little surprised to find that the skirt has a placket hidden under a pleat below the front button closure. A pleated skirt is, in many ways, more flattering than a gathered skirt - at least on me..

The suggested fabrics run quite a range: cottons, synthetics, blends, silk, linen, chiffon, brocade, lightweight wools, wool-crepe, wool jersey, and corduroy. While I'm sure any of those fabrics might work, they would all give an entirely different look and require different handling. I don't have a fabric picked out for this yet, but I'm leaning toward cotton. I'll have to look at my stash and see what might work. I'll also need to make a petticoat slip.

Even though the pattern has all the appearances of being my size, the measurements on the back envelope indicate I will have to make adjustments. This is looking more and more like a lot of work. Hmm... I do plan to make this up, just not sure when.

Simplicity 3295 and vintage pattern measurements

A reader asked a very interesting question

I have started sewing for my 20 month old son and some of his friends and was wondering if you have any experience with vintage patterns (1940's, 50's, 60's). Specifically I'm wondering if you have any thoughts on size variations. I'm sure you are familiar with the dramatic shifts in women's pattern sizes (the 1940's pattern size 12 is very different from the current pattern size 12)...I'm wondering if the same shifts occurred in children's sizes. Any thoughts you would be willing to pass on would be much appreciated!

This question was a little difficult for me to answer because I don't use home sewing patterns very often (not for children, anyway). They require too much work to correct. They have a lot of sloppy patternmaking. It is easier to pull out proven blocks and draft whatever style I want. I will buy a commercial pattern only when I have difficulty figuring out a more difficult design, such as a sleeper and then I only refer to it. I almost always draft my own patterns.

At one time, I thought a collection of vintage children's patterns would be pretty neat to have. I started collecting a while a go, but haven't added much to it. See, I don't actually look at the pattern pieces. Instead, I collect the patterns for design inspiration - in other words, I like the pretty pictures. I can draft patterns with the same style using my own personal blocks. This is one of the few vintage patterns I have from 1950.



I liked this pattern because it has an unusual skirt, pleated fullness in back and a gathered front waist. The bodice has a built-in cap/kimono sleeve. Besides, it is cute!

Now the question of sizing differences between then and now is also a difficult to answer. I haven't really done the research to be able to supply a truly adequate answer. I checked the measurements on the back of this envelope against my collection of measurement charts and the 1950 measurements fall within an acceptable range of contemporary measurements. In fact, the body measurements for this pattern were a little larger than today's measurements. I found this surprising considering the extensive reporting about childhood obesity. Of course, this is one style, in one size, from one company. I don't know how other vintage patterns may measure up. The best thing, of course, is to measure your own child and compare the measurements with the pattern envelope charts.

One difference that may exist between vintage and contemporary patterns is the amount of ease, design and wearing. Styles from the 1960's may fit closer to the body versus styles from the 1980's. This may cause one to think the patterns from the 60's were made to fit smaller people versus larger people in the 80's. The reality is that the prevailing styles influenced fit. It is helpful to try and look at the patterns from the correct perspective. Unless you are striving for authenticity, it is worth the time to draft your own patterns.

I haven't really seen a "vanity" sizing shift in children's clothing that is comparable to women's clothing. US Children's sizes are based on age designations. If anything, the sizing has become more specific. The 1950's may have had one infant size and then start with toddler sizing as 1, 2, 3, etc. Now, infant sizing is broken down by age too -- 0-3M, for example. Measurements are derived from the average measurements of children in each age grouping. Some consumers become frustrated by this sizing system because their children may vary from the norm (not to mention every manufacturer sizes differently). They may have a 2 year old child that actually wears a 4T. Trying on multiple sizes of one style can cause frustration in a changing room, if parents even take the time to try clothes on.

European sizing is evolving to a more intelligent sizing system. The Europeans are basing their sizing on height and weight measurements, available on hang tags and labels. Body size measurements are broken down by age grouping too, but they are not given age designations. This concept enables the consumer to buy the most appropriate size regardless of the age of the child.
