Fetman posted a total of eight photos on his Instagram account -- four dress selections for Vanessa and four dress selections for Raven.
But the girls ultimately had the final say when it came to what they'd like to wear while hopefully receiving a marriage proposal from The Bachelor star Nick Viall.
In preparation for what could have been the biggest night of their lives, both Vanessa and Raven chose one of the "proposal gowns" Fetman presented them, and all of the floor-length evening dresses were sexy, sophisticated and covered in embellishments.
"It could be the day you get engaged or it could be the worst day of your life," Fetman toldPeople. "I never want her to think, 'He didn't pick me because he didn't like the way I looked.'"
While Vanessa played around with different necklines, Raven seemed to have her mind set on a high-neck, sleeveless silhouette.
Raven tried on a white mermaid-style gown featuring pearls throughout and tulle at the bottom; a sparkly green, form-fitting halter number; a light grey or icy blue dress with sequin embroidery; and a black gown with a thigh-high slit, sheer panels and big rhinestones on the shoulder straps.
In a similar color scheme, Vanessa considered a strapless, ivory gown with floral embellishments across the bodice and a panel at the bottom of the dress; a tight black, V-neck dress covered in sequins; a sleeveless red-sequin halter gown with a slit above her knee; and finally a midnight blue, sparkly dress with a high neckline.
As shown in previews for the March 13 finale, Nick plans to propose to either the special education teacher from Montreal or the Arkansas boutique owner in the beautiful snowy landscape of Finland with a massive Neil Lane diamond engagement ring.
When Reality TV World asked Nick how his The Bachelor journey ended before Season 21 premiered in January, he revealed, "I think I can definitely say I found love. I won't be able to give you much more detail about that other than you'll have to watch and see how that played out and what it all meant. But I certainly have no regrets. I never look back. And regardless of how it all played out, I always look forward. I overall feel good about things."
Nick's season of The Bachelor concludes Monday night with a two-hour finale beginning at 8PM ET/PT, followed by the season's After the Final Rose special at 10PM ET/PT on ABC.
