Check out the style on this preppy, newly listed $12.5 million Long Island mansion.

They belong to billionaire Italian eyewear heir Claudio Del Vecchio and his wife, Debra Ann.

Built in 1916, the home at 393 Mill River Road in Muttontown, NY, sits on 8.1 acres.

The Del Vecchios bought the property for $7.5 million in 2012, according to records. It features nine bedrooms, eight bathrooms, four half baths and seven fireplaces.

Details include a formal living room and dining room with original moldings, a chef’s kitchen with a butler’s pantry and breakfast room, plus a great room with a stone fireplace.

There’s also an elevator, a wine cellar, an indoor pool and a dog spa.

Outside, there’s a generator, a five-car garage with radiant heat, a pool, tennis court, putting green, “English walled gardens,” and a children’s playhouse, according to the listing — from brokers Debra Russell and Cottie Maxwell of Daniel Gale Sotheby’s International Realty.

The Del Vechios “brought [the old manor home] back to life,” Russell said. “They restored it to its original old Gold Coast glamor.”

Now, she adds, they are leaving to move on to their next restoration project, which is also in Long Island. Del Vecchio famously bought Brooks Brothers for $225 million in 2001.

But the legendary American menswear company, which launched in 1818, became a COVID casualty.

It declared bankruptcy in July, during the height of lockdown and has since been sold for $325 million to Simon Property Group, the biggest mall operator in the US, and Authentic Brands Group, a licensing firm.
