There are lots of words men may prefer to "petite," but that doesn't mean we would think to buy our pants from the "dwarf tossing loop," no matter our proportions.
There's the "Big & Tall" shops and catalogs... is there a "Little & Short" counterpart? No. So what you need is something "normal," but where normal includes your dimensions. Have you tried shopping for pants in an ethnic enclave of people tending to have smaller proportions? New Jersey might work, but maybe there's a Chinatown closer to you.
