Regardless, Lange and fellow maternity designer Emilia Fabricant, of Cadeau Maternity and Babystyle, agree that the two extremes of celebrity choice reflect a greater reality. "It's indicative of how maternity clothes are today," says Fabricant of the market's increased styles. "There's so many different designers providing that service that allows a woman to actually choose which direction to go in when she's pregnant."
Designer Rachel Roy, who is expecting her second child with husband Damon Dash, appreciates the idea that a woman can easily stay true to her personal style during her pregnancy. Yet she wants to stay comfortable, too, and guesses that Lopez does as well. "It's hard. Some women live to be pregnant, and they glow," Roy says. "It's not like that for me. It's difficult, and your body goes through changes. You bloat and your feet are flotation devices and shoes don't fit and your skin itches because it's stretching. It's not something you want to slap something tight on."
