Mollie King thinks pyjamas can still look ''sexy''.

The 30-year-old singer has been announced as the face of lingerie giant Boux Avenue, and the blonde beauty believes nightwear is coming back and a two piece short set can be made to look less frumpy and more appealing to the eye than a raunchy negligee.

Speaking to the Mail Online about her style preferences, the blonde-haired beauty - who is known for being in the band The Saturdays alongside Vanessa White, Una Healy, Frankie Bridge and Rochelle Humes - said: ''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.''

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

She continued: ''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.''

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

She added: ''Clothes should be fun and we should be able whatever we want to, especially at home when you're in your comfort zone.''

Mollie is currently competing on this year's 'Strictly Come Dancing', and the style icon - who has been partnered with dance professional AJ Pritchard - has been having a ''ginger shot every day'' as well as additional vitamin supplements to help her fight any colds.

She said: ''I heard ginger was amazing for keeping colds away so I have been drinking ginger shot every day, alongside Berocca and Echinacea.

''It's worked so far, and I haven't been ill once. In fact, what with all the training we do - around 12 hours a day - I have actually never felt fitter.''
