- If you wash them the wrong way, they soon look old and drab.

- If you use Lux Flakes, they can stay lovely three times as long.

- Quite a difference isn't there? But it's true.

- Actual washing tests proved it. We purposely washed pretty slips and nighties the wrong way, you know with strong soap and too hot water.

- You should've seen them after thirty washings of that kind! Half their color was gone, and some of the straps and seams were frayed and pulled apart.

- But then we washed the same kind of undies in gentle lukewarm Lux suds, and they came out beautifully.

- Still colorful and lovely and new looking!

- Now I know you don't want to ruin perfectly good undies proving to yourself what wrong washing can do.

- So take it from me: Don't risk your undies with soaps that are strong, Lux keeps them new looking three times as long!

- After the play we'll have a chat with our stars.
