Which brand of designer church suits, should I buy

My friend told me about a really amazing website that sells womens suits. The only issue is that they have such a huge selection of brands, I don’t which one to buy. I’ve heard that lisa rene is hot right now but they don’t have a good selection of plus sizes. I also heard that Donna Vinci has some really elegant designer church suits that also look good. Those are the only two brands I familiar with so please help. My friends baby dedication is next month and I want to look my best since it’s her first child, which makes it a special occasion. Please suggest some other brands for my considerations. Thanks
