Melania Trump, 46, the Slovenia-born third wife of presidential candidate Donald Trump, took a rare turn in the spotlight at the Republican National Convention in Cleveland on Tuesday night wearing white.

And not just any white, but a figure-skimming (but not clinging) number by Roksanda, according to Women’s Wear Daily.

The frock featured a nipped waist, surprising chiffon poufs at the three-quarter-length sleeves, and an elongated zippered back. She reportedly bought it for herself from Net-A-Porter, where similar styles sell for $1,500.

The color projected purity and cleanliness (think brides and doctors), while the flirty cuffs underscored certain femininity, even girlishness — a likely calculated and perfect foil to the former model’s much-publicized British GQ cover in which she appeared naked. The designer, Roksanda Ilincic, is London-based and Serbian-born.

Trump, highlighted hair worn loose and wavy, added chunky diamond studs and nude suede stilettos to her ensemble — picture perfect, if not groundbreaking. So how did her dress rate among fashion pundits?

“She was very covered up and the dress was flattering without being vulgar,” said Robert Verdi, a celebrity stylist. “She probably suffered and struggled through the decision of what to wear. It was aspirational while still approachable . . . basically a shift with a wacky sleeve.”

He added, “It’s a dress that says ‘I’ve never done dishes.’ ”
