A pair of custom swimming shorts have been designed for Harry Styles by Fáilte Ireland, to encourage him to take a dip in the Irish sea.

When performing at the Aviva Stadium last year, the 29 year-old was spotted at Vico Baths in Dublin.

Fáilte Ireland’s Head of Marketing, Emma Woods, says the bespoke shorts were created to ensure the fashionista plunges in style during his trip.

‘Harry, like so many of us loves to take a dip in the Irish water,  so we’ve commissioned a special pair of swimming shorts for him and we’ve sent him a list of some of the best swimming spots in Meath and Ireland’s ancient eas, so hopefully you’ll spot him somewhere over the weekend.’
