Most stuff I've looked at describes the IT shape as broad shoulders/big bust, not much of a waist, slender hips and legs.
Angie's description is a bit different - she says you're an IT if your shoulders are broader than your hips, regardless of the waist (ie you can be an IT with or without a defined waist). THis is helpful, because otherwise, where do you fit if your shoulders are big relative to your hips and your waist is small?
So I guess an IT with a defined waist could think of herself as part hourglass, part pear. But I've never seen you in anything with a lot of waist definition, AG, for whatever reason ...
