IVANA AT NO LOSS FOR PLACE TO HANG HER HAT.

Byline: PHIL ROSENTHAL

Ivana Trump, now Ivana Trump-Muzzacchelli - or, better still, just Ivana - is currently hard at work on a self-help book on how to launch a business.

Her own House of Ivana line of clothing, cosmetics, jewelry and perfume is thriving. Of course, she undoubtedly has found that a $20 million divorce settlement from The Donald has made everything a little easier.

"When I did get my divorce, I said: 'I'm not poor. I can really do whatever I want to do. What is it that I always wanted to do but never could?' " Ivana said in an interview from her hotel suite in Aspen, Colo., to help promote CBS' adaptation of her first book, the novel "For Love Alone," set for 9 tonight on KCBS (Channel 2). "This is (also why) I started to write the book."

Money has made everything possible for this Czech-born 46-year-old, and it just keeps rolling in.

But of all the hats Ivana wears - including celebrity divorcee, entrepreneur, home-shopping saleswoman, jet-setter, former ski champ and mother of three - it is the one she wore six weeks ago in going from being a Trump to being Mrs. Riccardo Mazzucchelli that has caused the most talk of late.

"Here comes the bridle," was Time magazine's assessment of the asymmetrical white voilette from designer Thierry Mugler, as if Ivana would care whether her sense of style goes over most people's heads or not.

"You always find some people who might not like that, but that's just too bad," she said through an accent she still can't shake, English being the last of her seven languages. "You can't please everybody, and I don't intend to please everybody."

Part of her success has seemed to come from the fact that she never has.

"I don't think I ever lost my identity to my husband," she explained, with a laugh. "Not at all."

The outline of "For Love Alone," which was her first stab at a novel and landed in The New York Times best-seller list briefly in 1992, will sound familiar to anyone who knows her story.

It's a Danielle Steel-esque tale of a Czechoslovakian skier who comes to America and marries a wealthy businessman. The CBS version stars Stephen Collins, Madeline Kahn and Sanna Vraa as the Ivana vanna-be.

The real Ivana has a cameo along with new husband Riccardo, an Italian businessman who seems to be more than willing to rearrange his life for her. It's not a bad life, really.

This Aspen vacation over New Year's, for example, has been made into a business trip by Ivana hitting the slopes with ski star Andy Mill, husband of tennis pro Chris Evert, for a prospective TV special.

Afterward, it's home to New York, though Ivana also has places in Greenwich, Conn.; Palm Beach, Fla.; and London. "And I have bought a monster boat," she said. "I'm probably the only woman in the whole world who would buy herself a (35-meter) boat.

"It's a pain, but I adore it. I have been around boats. I understand quite a bit. My father was an engineer, so I'm very good at engineering stuff, believe it or not. I know about technical things."

Perhaps there's another book in it for her.
