Halloween costume ideas - Fergie shows some leg.

What are some of the Halloween costume ideas for 2012 from Hollywood stars and other famous celebrities?

Check out our photo gallery below for many of the celebrities dressed for trick or treat from last Halloween and you may notice that Halloween for many adults equals skimpy costumes and sexy attire.

Dolly Parton says that is the route she will go this year - she is going naughty.

The country music legend picked up a very sexy costume from the infamous Trashy Lingerie store in Los Angeles earlier this month and is planning on putting all the emphasis on her best assets when the spooky holiday happens next Wednesday.

Dolly told TMZ.com, ''We have fun at Halloween'', before grabbing her ample breasts and adding, ''I have two pumpkins ... that's all I care about!''

The '9 to 5' singer is hoping to spice things up for her husband Carl Thomas Dean with her Halloween antics and keep their 46-year marriage exciting.

Dolly, 66, wed Carl Thomas Dean in May 1966 and she credits their married bliss to the fact they have no children and are financially comfortable.

She recently said: ''Mutual respect, shared interests and the fact that I stay gone a long time! Not having children together, and not having money problems has probably helped.

''A lot of the pressures that cause couples trouble are just things we never had to go through.''

The star also confessed she likes to flirt with younger men, joking: ''But I am a flirt, and I do get younger men flirting with me too.''
