I went back and looked at the proportion section of The Triumph of Individual Style. If you are able to get hold of a copy of the book, it’s very dense with useful information. The most pleasing proportions are the 2:3 and 3:5 ratio’s. Forum members have been correct in saying individual adjustments are needed if your vertical proportions are not ideal. So, how do you know if your proportions are not in keeping with this elusive ideal?
Solution: 1. Measure the vertical length of your head with a string. Divide that into your total height. If your answer is 8, your head is in perfect proportion to your body. If it is more than 8, than your head is short in proportion to your body. If your answer is less than 8, then your head is long in proportion to your body.
I did this and discovered that my head is slightly short in proportion to my body. My result was 8.3. I assume this is why my hair stylist and I prefer hair styles that increase volume on top of my head, making my head look longer. It’s odd, because if you isolate my face without considering my body, it has a long narrow shape!
2. Upper torso: Use the string to measure from the chin to your waist. If the result is twice your head measurement in number 1, your torso is in proportion. If it is less than two head lengths than you are short waisted. If it is more than two head lengths you are long waisted.
Surprise for me here! I am short waisted. My result was 1 less than ideal.
3. Rise: Measure from the waist to the crotch. If your rise is one head length you are in proportion, if it is less than 1 head length you have a short rise. A long rise would be more than 1 head length.
No surprise for me here. My rise is longer than my head length by 2 inches.
4. Legs: Measure from crotch to soles of feet.
If result is 4 head lengths you are in proportion.
If result is less than 4 head lengths your legs are short.
If result is more than 4 head lengths your legs are long.
My legs are slightly long, by 0.5.
There are a lot of ways to learn about proportions. I know Imogen writes about them as Angie has mentioned. Since I tend to be an analytic thinker the measurements work best for me. I also found some blog posts from a company called The Fashion Code. I think there are enough clues in the pictures that there is no need to make any purchases.
By the way. The Triumph of Individual Style goes further in helping identify what to do with less than ideal proportions, and then has a section on collars and necklines.
