If there's one hot mama in Hollywood who knows a thing or two about looking chic while on-the-go, it's Matthew McConaughey's wife, Camila Alves. A busy model, mom and handbag designer, Alves, 30, tells Us Weekly her home life is often akin to a "traveling circus," but that with a few key wardrobe pieces, she can make it through any mommy mishap -- or triumph -- with flying colors.

"If there's one thing any mom should have for fall, it's a peplum top," says Alves, who wore a red top and matching skirt for a date night out with McConaughey in New York City. "It's a trend now that's going to be around. If you're petite, it will give you curves and be flirty; if you're just having a bloated day -- we all have those -- or just gave birth, it's very forgiving."

As the weather changes, California cool Alves suggests seeking out a blazer or jacket with just a hint of eye-catching detail, like this beaded version she wore to sit front row at Tory Burch's Sept. 10 fashion show in NYC. The best part of having a topper with built-in accents? It'll go with any neutral in your closet. "You can pair it with anything!" says the model.

Like any woman, Alves knows that the perfect handbag can make even the best outfit even better, and luckily for the model mom, she has her very own handbag collection -- MUXO -- to choose from when stepping out for the day. Designing the line with her mom, Fatima, for the last eight years, Alves will unveil her latest collection live on QVC Fri., Sept. 13 at 7 p.m. (EST)

As Alves -- who switches between her cross-body snake print bag and a larger slouchy leather hobo -- explains, she makes her bags functional because she knows what busy moms need. "The bags are very practical, with all these hidden pockets and compartments," she tells Us. "They're there but part of the bag so you don't have to look like a bag lady."
