They were not. Fashion designers started as chitinous eggs, in which the mother fashion designer builds a humid, temperate incubation chamber for them to mature while fighting off predators. After the incubation period is complete, the fashion designers break free from their hard shells, their exoskeletons still not fully formed. It's essential at this stage for them to feast on living flesh, so the newborn fashion designers leave the nest to hunt for sustenance. At this point, survival rate is only 10% as there usually is not a sufficient amount of nearby food for all the hatchlings and only the strongest survive. But that is just part of the life cycle of a fashion designer.
