When Hallmark star Andrea Brooks spoke to TV Fanatic about filming "When Calls the Heart" while pregnant, she commended Barbara Gregusova, who does costumes for the show, on her work in helping hide the pregnancy. "She's so good with angles and cut clothing in ways I had never thought about," Brooks raved. She also told Gregusova she wanted to interview her about her talents. "She really has so many fantastic ideas for covering a pregnancy," Brooks said.

In addition to costumes and props playing a part in hiding Brooks' baby bump, the actual scripts of the show helped as well. "We wrote scenes in interesting ways that everything could be hidden," Brooks told the outlet, "but it really becomes this extra element that, on top of your character, your performance, your story, and all the normal things that you worry about." 

In an interview with TV Goodness, Brooks also said the costume designer saved costumes from when Brooks was pregnant with her daughter, Viola during the filming of Season 7. "[Gregusova] said, 'Just in case, I figured if you ever had another kid,' which was amazing," Brooks told TV Goodness. Unfortunately, the actor said certain costumes got very hot since she was pregnant, making her want lighter-weight clothes no matter the weather or season.
