I cannot find this sci-fi story that was publish in an issue of OMNI magazine. It is in a time when humans can have any form they wish. It starts with a party of transhumans who invite their guests to pick a form for their child to me. And the shock of the party is that a woman submit a normal human form and it considered rave, very cool - but not used. And it has to do with a male transhuman who becomes obsessed with this very hip woman-creature who would dare submit a human form. He is shocked and dismayed, heart-broken when she goes to Kathmandu and takes on this base human form. He gets over it until this wasp-combination laughs at him at party - and he knows it is her.
I cannot get this story out of mind but I cant' find the issue it was in. Please help. It was great story
