Jackie After Jack

Subtitled Portrait of the Lady (pshaw), this tacky but toothsome bio fecklessly reenacts how, sucked into the vortex of Kennedy tragedy, the former Miss Bouvier dealt. She drank. She puked. She slept around (allegedly bedding both Marlon Brando and Warren Beatty). And she shopped. Oh, how she shopped — so overwhelming one salesman, he was sent to bed with a sedative. Andersen may be on a cucumber-sandwich basis with ''Tish'' (social secretary Baldrige) and ''Yusha'' (stepbrother Auchincloss), but a fine-knit narrative can't stop Kitty Kelley's marabou mantle from settling inexorably around his shoulders. Indeed, he seems to have succumbed to the spirit of quite a different Jackie: Collins. C+
