If you like sexy lingerie but think it's a waste of money because your partner can't see it when the lights are out, we have a fun solution for you ...

Glow in the dark underwear!

The high-end undie line, Cosabella, has come out with lacy lingerie that lights up in the dark (provided you hold it under a lamp for 10 minutes before turning the lights off).

And it ain't exactly cheap either.

One set of alien underwear will set you back about $150.

We suggest some glow tape and a string of Christmas lights for those of you who like the idea but don't have the cash ...
