Data point: My girlfriend is a tech designer who's worked at Guess, Hot Topic, and a slew of smaller companies. She absolutely loathes the working environment because of the drama and bitterly regrets getting into the industry. She's considering going into customer service in a call center(!) (a 50%+ pay cut) because the work environments are so stressful in the fashion industry. She explicitly blames it on the gender balance being so female-dominated.
