Pop-rocker Avril Lavigne has teased details of the dress she's planning to wear during her forthcoming wedding to Nickelback's Chad Kroeger.

The pair announced their engagement back in August and the 'What The Hell' songstress has now explained to People magazine that her gown will be made up of parts from different dresses and if that doesn't work out she'll plan something else just as unusual:

"I have an idea of what I want. It might be something that I buy a few different dresses and rip them up and put them all together and dye them, or maybe I'll kind of do a collaboration with another designer."

She added that her engagement ring is one accessory that goes with everything and she "can't take it off": "I can't take it off. I sleep with it on. It goes with every outfit. Get engaged, it's the perfect accessory for every Outfit. I did it. You should, too."
