Couple laughing in bedHalloween is party time for many and the search for a unique and fabulous costume is well and truly on.

But forget the stunningly sexy witch costume you're contemplating... if you really want to stand out (in the bedroom that is), then it's glow-in-the-dark underwear that you need.

The brainchild of designer Jan Hawley who runs Luminglow from her home in New South Wales, Australia, the bra and knickers set look like any ordinary underwear by day.

But by night, given a couple of minutes held against a light, they'll be glowing green.

Jan told the Daily Mail: "In this range the underwear is much smaller and sexier. We've called it the Boudoir collection because it's strictly for the bedroom after dark.

"How long does the lace glow for? Well, probably long enough!"

Well quite. It might be a bit of fun, but for Jan it's a full time business. Luminglow underwear is now being sold around the world, including in the USA and Europe.

Strangely, it is Jan's sons that deserve some of the credit.

"After the success of the original collection, my sons started taking a keen interest," she says.

"I took their ideas on board and now we seem to have very tiny knickers and bras that show a lot of cleavage.

"But at the heart of the collection, it's still a bit of a giggle."

And we're guessing there will be more than a few giggling couples in the bedroom this Halloween.
