Cue the Wedding March! Former Bachelor stars DeAnna Pappas and Holly Durst are picking out their wedding dresses in preparation to marry the Stagliano twins.

This double wedding embodies the "it's a small world" reality of the Bachelor franchise. A quick history: DeAnna Pappas was the last girl standing on The Bachelor Season 11 when Brad Womack decided he'd rather saunter back to Texas alone. Now he's getting a second stab at being The Bachelor on Season 15 in January. DeAnna then became The Bachelorette and chose Jesse Csincsak. They were engaged briefly, but soon broke up. Jesse eventually started dating Holly Durst, who was on Matt Grant's The Bachelor: London Calling. After Holly and Jesse broke up, Holly and DeAnna ended up bonding over their shared (bad?) experiences with him.

Meanwhile, Michael Stagliano was on Jillian Harris's Season 5 of The Bachelorette. When he wasn't picked, he ended up dating Holly Durst. To complete this whole tangled web, DeAnna began dating Michael's twin brother, Stephen, who has no other relation to The Bachelor franchise. The four of them announced their joint engagements in the same week that Jesse announced his own engagement to a past Bachelor contestant. Coincidence? We think not.

And now future sisters-in-law DeAnna and Holly are shopping for wedding dresses. Entertainment Tonight tagged along as the ladies watched an Alfred Angelo fashion show and tried the dresses on for themselves. "I'm going mermaid," DeAnna says of her bridal style, while Holly says, "I'm going more of like a Cinderella dress, ball gown, [style]."

Could they end up picking the same gown? DeAnna laughs, "We think that could be a problem. We'll duke it out."

"I've never tried on a wedding dress in my entire life so I can't wait to just put the first one on," Holly says. "I'm hoping that it's the whole beginner's luck [thing] and the first one I put on, I fall in love with."

Speaking of love and luck, DeAnna jokes, "We're hoping that the four of us still love each other when all of this is done."
