Classy! Kitty’s £2,295 outfit reveals her pants

PRINCESS Diana’s high-spirited niece, Lady Kitty Spencer, could not conceal her curves when she went to a bash at the Dorchester hotel this week.

Dressed in a £2,295 Temperley London Wild Horse turquoise sequin jumpsuit with flared sleeves, the 26-year-old charity ambassador looked the model of sartorial elegance from the front (left) — but from behind, it was a different story.

Unknown to Lady Kitty, her outfit revealed exactly what she was wearing underneath (right).

Kitty separated from her long-term boyfriend, property tycoon Niccolo Barattieri, 45, earlier this year, so he was not around to preserve her dignity.
