I did the string test this morning. Thanks Suz! Here are the results:

My bustline is slightly lower so measurement 2 (chin to bust) is a little long.

Surprise! I am a bit LONG-waisted (bust to waist is longer than a length, but not by much) AND long in the rise - this explains why low rise pants are such a nightmare for me, which I knew but didn't understand - I assumed it was because I had no waist. This assumes I know where my waist actually IS.

My legs are overall proportionate but I'm long in the calves, which I did not expect at all. Again, that explains why I can wear boots with a relatively tall shaft (15" - 16") for my height of 5'1".

Very enlightening! Now I need to know what to adjust wardrobe-wise. Seems like cropped jackets and sweaters are my friends, mid-rise jeans work best, and I need to fill in the space between chin and bustline more (which is maybe why I don't like low scoopnecks?). I also see Imogen recommends not tucking with this body type which is also in line with my preferences! Other suggestions?

Very cool exercise!
