Lady Amelia and Lady Eliza Spencer, nieces of Princess Diana, are at it again.

The twin sisters, daughters of Princess Diana's brother Charles Spencer, have been making very stylish appearances at Milan Fashion Week events in recent days.

Amelia and Eliza showed up to the 60th anniversary celebration of Vogue Italia in their latest stunning look, wearing matching oversized white tailored suits as dresses instead of pants. Both were by Elisabetta Franchi, whose brand co-sponsored the event.

Amelia's suit dress was white satin with a deep V and only two buttons. She paired it with a black strappy stiletto and a black clutch bag.

Eliza's double-breasted suit, on the other hand, was slightly longer than her sister's, with a higher neck and two buttons in a row, making it look like a formal coat, but it was playful with bare feet, white pointy stilettos, and a black clutch bag.

Both wore their blonde hair in tight low ponytails.

In Milan, Elisa and Amelia also attended the Elisabetta Franchi runway show.

Amelia wore a sparkling one-shoulder draped floor-length dress by the same label, while Eliza wore a tight-fitting gown in the same color with gorgeous cutouts around her midriff.

Amelia and Eliza also attended the Versace show in Milan.

Lady Amelia chose a sexy, form-fitting knee-length black leather dress with a corseted bodice, paired with black pants and a black handbag. Lady Eliza opted for a tailored black pantsuit, black handbag, and pointy black stilettos for an evening twist on business casual.
