"Of all the reader questions I get each week, the most common question I get is, 'What are you wearing?'" says advice columnist Katherine Schwarzenegger.

It's no wonder: The 25-year-old author of Rock What You've Got: Secrets to Loving Your Inner and Outer Beauty From Someone Who's Been There and Back knows a thing or two about the importance of feeling comfortable in your own skin. And when it comes to what you wear, its all about dressing for your body type and not falling victim to trends that don't suit you—something Kat learned firsthand.

"An example of a trend that I tried that didn't exactly work out would be high-waisted jeans," she says. "We see them everywhere, but what I realized is that they don't work for every body type."

So what trend does work for her? Jumpsuits. "I could wear them all day every day and I absolutely love the way they feel and the way the make me look," she shares. And that, Kat emphasizes, is the key.
