Nicki Minaj, Jennifer Hudson, Rihanna are among celebs at splashy Versus Versace runway show

Talk about your one-stop shopping.

If you liked the sexy numbers on the Versus Versace runway Sunday night — many of them tight, short, black, and embellished with gold hardware — you could purchase them the moment the show ended. All the outfits were on sale at VersusVersace.com.

Such immediate shopping looks to become a Fashion Week trend — BCBG MaxAzria introduced a similar initiative at its show last week, though not every single look was available. It appears that designers want to instantly capitalize on the buzz surrounding their new collections — and not wait for others to knock off their looks (often for less money) before they've had a chance to sell them.

Not surprisingly, the Versus Versace event, at a club on the far west side of Manhattan, drew a bevy of celebs. Rihanna was there, as was Nicki Minaj, Jennifer Hudson, supermodel Naomi Campbell, and young TV stars Bella Thorne and Victoria Justice. Donatella Versace, of course, was on hand to welcome everyone.

The new Versus Versace line, less expensive than the company's high-end line, was designed by Anthony Vaccarello. His collection had lots of sleek-fitting numbers in black, featuring gold buttons, lion's head piercings, buckles and breastplates. There was also a trim with a Versace Grecian key motif. And there was a rock-star metallic gold jacket.

But probably the most evocative piece was a tight, one-shoulder black dress that had an entire body-length slit held together with clasps — recalling the famous Versace safety pin dress worn by actress Elizabeth Hurley at the 1994 premiere of "Four Weddings and a Funeral."

There were several men's items as well — a black leather vest, for example, or white sneakers with more of that gold hardware.

After the runway show, guests went upstairs for a star-studded after-party.
