Hilary and Haylie Duff pose in cleavage-tastic bikinis together: See the pics from their sisters' weekend!

Hilary and Haylie Duff got to spend lots of quality sister time together over the weekend. The actresses attended the wedding of mutual friends at the Ocean Club Fairmont Resort in Bermuda, and took the opportunity to enjoy some beach time.

"@erinlhaggerty you were the most beautiful bride! We love you," Hilary, 28, captioned a black and white picture with the bride, her sister, and a pal.

The sisters wore bold printed ensembles for the picturesque wedding, posing with pals in a series of photos.

Later Haylie, 31, goofed off with her younger sis, sporting Snapchat's duck face filter from their hotel room.

Both of the sisters also posted beachside photos in their bikinis. Haylie sported a white two-piece, while Hilary showed off some cleavage in a floral-printed bikini top.

In June, Hilary told Today.com that she doesn't put pressures on herself to be in shape for swimsuit season.

"I don't care to look absolutely perfect in a bathing suit," she said at the time. "I'm a normal girl. I'm strong. I'm fit. I feel good about myself after I've had a baby."

Hilary has been extra busy lately as she films the next season of her TV Land comedy Younger with co-stars Sutton Foster and Nico Tortorella in NYC.

"My beautiful friends – beautiful on the inside and out @youngertv @nicotortorella @hilaryduff," Foster captioned a selfie on set last week.
