Pyjamas can look sexy, says Mollie King

"The pyjama is back. They don't have to be old, frumpy things any more. Certainly, with me, it's a case of any excuse to wear them and nowadays there are so many options, anything from little cotton shorts and T-shirts to silk pyjamas. You can look just as sexy in shorts and a T-shirt as you can a little negligee," King told dailymail.co.uk.

The "Hair down" hitmaker thinks women shouldn't feel they have to wear "something sexy" to excite their lover in the bedroom.

She said: "What's appealing in a woman, or a guy, is an inner self confidence, intelligence and humour; it's not about dressing up in something sexy."

She thinks the most important thing is for people to have "fun" when they are choosing their outfit.
