Interesting thread and so hard to respond without getting into psychology.
Growing up, I had a mom who was a pretty pear and a big sister who was a VERY curvy hourglass with a "perfect" (so I heard, over and over and over again) 36-23-36 figure. I did not develop a chest until my 20s - I was more of a rectangle shape, except more of a soft rectangle, if that makes sense. I wore my sister's hand-me-downs and that did serious damage to my head, as I just didn't fill them out like she did, and the waist was constricting. I identified with my mom, since I didn't have much of a chest, yet I just didn't have the tiny waist and beautiful hips like she did.
I spent years and years wishing I had either a pear or an hourglass shape, and thinking these were the "ideals."
I consider myself a YLF graduate as well, and over my YLF journey I have learned to embrace my figure and celebrate it through fashion. That includes my chest and yes, even my waist!! I may have a 0.8 waist/hip ratio, but I still have a waist.
With that said!!!
At some point in the journey I realized that my body type is, in reality, fairly well proportioned. For me, this was quite the revelation. I have a hunch, Khris, when you arrive at your final weight, you may be the same.
I am a bit of this and a bit of that: a bit hourglassy but not quite (since my waist isn't teeny tiny, but my shoulders and hips ARE equal, even if it doesn't "eyeball" that way). A bit inverted triangle (I do gain weight first in the upper body, and my shoulders are quite strong while my hips are narrow). A bit apple (squishy belly).
What that means is that it is not too hard to create whatever silhouette I feel like creating for that day!!
Add a boyfriend jacket over skinnies.... I am an inverted triangle.
Wear form-fitting top and a cardi buttoned at the waist, and I'm an hourglass.
Wear a form-fitting top with an A-line skirt, I am a pear.
Lose my waist in a long flowy, sleeveless top over skinnies, and I'm a (busty) rectangle.
Does one formula flatter better than the others? Probably. But who cares. I like the ability to adapt to my mood and reinvent my figure whenever I want.
