Ok I've narrowed that list down to 4 choices:

Starbunz Super Undies from DDU at $24

Happy Heiny Pocket Trainers from DDU at $26.95

Bummis Trainer Pants from DDU at $16 for white, $18 for print

Little Beetle Training Pants from NN at $20

For the shape, I'm thinking Starbunz, more smooth and trim. Most of them need stuffing. I'm hoping my Kissaluv boosters that I've ordered will be useful. I'd rather get some that can absorb at least one wee. What do you all think?
