The perfect Instagram sister must manage the overlap between her personal and professional life. Since Mona works with her family, that presents a certain set of workplace challenges. When asked if she treats her sisters any differently when they're on the clock, Mona said, "I think that's impossible. You can never shut off from the responsibility of owning a business, and I don't think we necessarily need to shut off from being partners to be sisters."
One problem that overlaps both their personal and professional lives is, unsurprisingly, makeup. "We still play tug-of-war over a new product that one of us gets first, even though we both have so much."
But Mona insists that she likes to keep everyday makeup light. Her personal go-tos include mineral foundation, mascara, eyeliner, and lipstick. If she's feeling fancy, she might add a "light contour."
