I'm obsessed with Isabella Oliver, the prices are not cheap, however, I found that everything I bought can also be worn when I'm not pregnant so that justified the price for me. And a lot of women who review their products online say they continued to purchase product from there even after they were pregnant. And the quality was great. I bought the ruched black midi dress to wear to formal events. I don't like what they have to offer at old navy or gap.
I didn't know Boden had maternity! Going to check that out now, I love their baby clothes.
