That's a wicked look! Bette Midler, 68, shows off her cleavage in glitzy witch's gown for her Fellini Haluweeni gala

It's a huge Halloween costume party for around 1,000 guests at the Waldorf Astoria, one of New York's ritziest hotels.

And Bette Midler, who organises the annual fund-raiser for the New York Restoration Project she set up, looked ready to cast a spell over Friday evening's proceedings, dressed as a very glitzy witch from Wicked.

The 68-year-old showed off her still handsome decolletage in a black, figure-hugging, sequin gown with a low neckline and black high-heeled shoes.

She popped a black witch's hat over her blonde hair and added a pop of colour to her look with bright red lipstick. 

Celebrities at the star-studded ball included Debra Messing, Martha Stewart, Billy Crystal, Katie Couric, former Mayor Michael Bloomberg, Chevy Chase, John Lithgow, fashion designer Michael Kors and his Project Runway co-host Nina Garcia, Phil Donahue and wife Marlo Thomas among many others.

Bette hammed it up on the carpet, posing with Kors and his husband Lance LePere, who had come as paparazzi.

Lithgow and Chase both looked like they were channelling artist Andy Warhol in dark glasses and blond mop wigs.

Meanwhile, Bette's husband of 30 years, artist Martin von Haselberg, was almost unrecognisable in a smart tuxedo with his face painted like a giant sunflower.  

The bash, which Bette has thrown for 19 years, was a little different this year.

Normally billed as a Haluween ball, combining Halloween with a Hawaian theme, the 2014 event was a Fellini Haluweeni, honouring the 21st anniversary of the Italian filmmaker's death on October 31, 1993, aged 73. 

Guests were invited to plan their mandatory fancy dress accordingly, with Kors giving a prize to the best costume. 

Bette founded the New York Restoration Project in 1995, which is devoted to making the city a greener, cleaner environment, with parks and public spaces within easy walking distance of homes.
