Christina Applegate’s chic, relaxed style has won her our vote as one of our favorite Hollywood fashionistas — and now we know all her secrets to staying stylish. For In Style‘s latest issue, which hits stands tomorrow, the Samantha Who? star reveals her favorite fashion tips. “I love sophisticated fashion, and I also love to be funky,” she tells the magazine of her ongoing style evolution. But, she reveals, “I don’t follow trends. I like things that are a little bit off and a little bit interesting.” And, in her quest for a distinctive personal style, being able to feel good in even the most casual clothes is one talent she’s perfected. “I have a friend who always calls me a chimney sweep because I tend to dress like one,” she jokes. “I don’t like doing my hair, so I wear the same cap every day–an ugly tweed old-man’s golfer’s cap.” Yet regardless of whether she’s dressed up or down, Christina knows that looking good is all about dressing for your body. “I think that if you’re wearing something that isn’t you, you’re just uncomfortable. I know what is going to look good on my body. I don’t want to be concerned all night about whether or not it fits or if my backside is hanging out.” And her favorite go-to items to cover that backside? “I believe in black pants because anything goes with them. I also think it’s important to have great jeans that fit your body. I can’t do the skinny jean. I just don’t have the body.” Get the full story tomorrow — and learn how she stays so fit! — in In Style‘s new Look Your Best issue or watch a video with her on Instyle.com now.
