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.

Not to be outdone by Cavalli or Dolce & Gabbana, Jean Paul Gaultier is the latest designer to lend his couture expertise to create custom-made costumes for a singer. The designer has created eight haute couture looks for Kylie Minogue’s “X” world tour that kicked off last night in Paris. Kylie opened the show in a purple chiffon gown from Gaultier’s 2006 collection that was completely couture modified to fit her. Some of her other dazzling outfits include a blue and white “K” logoed cheerleader- and football-inspired outfit complete with padded top, shorts and high heel sneaker shoes. She also showed off a long red satin dress, an equestrian-inspired look that included a black long tailed coat with fringe and over-the-knee leather boots, a sexy Geisha outfit with long Swarowski crystal mesh sleeves, a long turquoise gown with coral heart embroidery, a navy sequin sailor outfit, and finally a crystal embroided corset and black satin pants. With all these amazing costumes, we can’t decide which one is our favorite — maybe the Geisha? Tell us: What costume sounds best to you?
