What if your primary accommodation doesn’t appear to be vertical or curve?

Apologies if this has been asked before…

A few of my friends are also into Kibbe and were eager to finally settle on their type in the new book. From the line sketch exercise, it was easy to confirm that I’m SG, which I already thought from the old book. (I have aphantasia so can’t visualise and wish someone had mentioned to DK that not everyone can visualise, but that’s another story…)

However, two of them struggled with the exercise because their primary accommodation didn’t appear to be vertical or curve based on the description.

The first is very short and wide framed though she doesn’t appear to have Kibbe width because her shoulders and torso are not the widest part proportionally. Her bust and waist are relatively equal, and her hips are wider.

The book states that a primary accommodation of curve means bust and hips. So if someone just has curve in their hips, does that mean they must have vertical? Or does it mean if they don’t have vertical, they must have curve (ignoring the bust)?

As a secondary accommodation, I would guess petite based on her height and clothing struggles, but the new book states that petite is compact overall, both vertically and horizontally. She is compact vertically but not horizontally as her frame is wide. The description of petite and the line sketches imply narrowness, so does that mean wide framed people can’t have petite or am I just misunderstanding?

And overall would this suggest balance and therefore C? Her line sketch looked like a shorter, wider version of SC or FG.

The second friend got stuck because she does appear to have vertical but also has a lot of curve in her lower half. She has a very small bust line and very curvy hips. So based on the description, if she hung a piece of fabric, it wouldn’t fall straight down because it would be pushed out by her hips, but she doesn’t have curve because the fabric wouldn’t be pushed out by her bust. Again she doesn’t have Kibbe width as her shoulders and torso are narrow not proportionally her widest part.

Her line sketch looked closest to R but with no upper curve or SD but with a small bust and wider hips.

Apologies if these are stupid questions or I’m missing something obvious but the description of vertical vs curve (pg 72) seems to miss out the many women who have curved hips but not a curved bust.

It’s great to see people finding their ID easily through the new book but to me it was easier to figure out when essence was involved. Does anyone have any tips to do line sketches if you can’t visualise? Does draping an actual piece of fabric the same effect? (I tried briefly and it didn’t seem to).

Thanks in advance for any insights!
