Lauren Sánchez and Emily Ratajkowski both love these sexy butterfly dresses

These flirty frocks are taking flight for summer.

Lauren Sánchez rocked some colorful style as she enjoyed a date night with her billionaire fiancé, Jeff Bezos, in Portofino, Italy on Monday — and it turns out her butterfly-print dress is also beloved by Emily Ratajkowski.

The former news anchor sported a green Mirae Paris dress with a vibrant butterfly pattern as she joined the Amazon founder and their respective children for dinner on the Italian coast.

While her exact strapless style is sold out, the label offers a similar green dress ($450) with a one-shouldered look and an asymmetric, ruffled hem.

Sánchez accessorized her dress with a pair of aviator sunglasses, diamond studs and a pendant necklace, wearing clear heels that showed off her white pedicure.

The journalist carried a red handbag and a denim jacket in her hand to ward off the evening chill as they dined at celebrity fave Ristorante Puny.

Meanwhile, last July, Ratajkowski sported a hot pink cowl neck style from Mirae, featuring a similarly bold butterfly print as Sánchez’s.

Bezos and Sánchez have been spending time in Europe on his $500 million megayacht after Bezos popped the question to his girlfriend of five years last month, presenting her with a massive diamond ring that could be worth around $2.5 million.

The soon-to-be Mrs. Bezos also sported a much more casual look this week, wearing an Alo Yoga Airlift Suit Up Bra ($74) with matching Airlift High-Waist Suit Up Leggings ($138) for a stroll around Portofino.

However, she potentially gave a peek at her bridal style shortly after their engagement, sporting a pearl-embellished white minidress.
