Successful Dutch invention 'La Decollette,' a bra against vertical wrinkles on the cleavage, has been launched in Belgium, the UK, France, Spain and Germany.

"Many women who sleep on their sides, discover wrinkles on their cleavage when they wake up," said La Decollette founder Rachel de Boer. "At a certain age, often in combination with sun damage, the wrinkles intensify or don't disappear at all."

Her patented bra, which places fabric between the breasts for support and closes at the back, keeps all in place while sleeping. "The vertical wrinkles appear because the breasts are pressed against each other [...]," de Boer explains. "If you put some kind of support between the breasts you prevent the cleavage from wrinkling."

The bra is a one-size-fits-all thanks to its adjustable shoulder and back straps and sells for €49.99 online.
