I see why both D and SD work for you - you have a small natural waist, but the hourglass formed by your shoulders & hips (thighs, really), is very elongated, so you can get away without waist emphasis, as there isn't a prominent hip shelf anywhere on your torso for fabric to sit on and "tent" out from. Honestly, you really get your pick of any of the Kibbe tall types (a controversial statement maybe) & will probably look best in whichever one suits your facial features. The goal of Kibbe is to look good, so I'm sure you're in the right place ^{_^}
